[QUOTE=Happy5214;572823]OK. Overall, the high-level design looks nice, but here comes the nit-picking:[LIST][*]The document dates should be in <p> tags, likely generated by the JavaScript code.[*]My CSS class name changes were made for semantic reasons. One-letter class names are categorically bad and almost never acceptable.[*](Something I missed in my own edits) <thead> and <tbody> containers should be added where appropriate. (I already see a <tfoot> in the only necessary place.)[*]Fix the closing <thead> in line 125.[*]The jQuery code can probably be simplified a bit, and I'm curious why Karsten used an older version (3.3.1) than my demo (3.5.1).[*]The link/button table should not be a table, as it contains no tabular data and is purely for layout. It should use CSS for the same effect.[*]The contributor list transclusion should probably be an iframe.[*]The style attributes in the Definitions <th> tags should be replaced with scope="col" for the same effect (since that selector already has that style applied).[*]Delete the empty <p> between the contributor list and the Navigation <h2>.[*]Change the Navigation <section> tag to <nav>.[*]Enclose the Links and statistics sections in <section> tags.[*]Close the last <section>.[*]Add <header> and <main> blocks.[*]Since each base is its own page now, the stats should be a separate section rather than a one-line paragraph.[/LIST]
I know that looks like a lot, but as I said, the design looks great.[/QUOTE]


OK, I think all of these remarks are going to take some time to be addressed, if at all possible.
Personally, I don't even understand them.
Let the competent people have time ...

If other people have other suggestions : don't hesitate.

Page updated.
Many thanks to all for your help.

[B]Added bases :[/B] 45, 75, 105, 231, 15015.

We now have 71 bases in total.

To the new appearance of the page:
Almost all points cleared but not (yet)
- scripts for button function codes simplify
- 'table' with links/buttons as css

Those changes can be done later but the most work now is to redesign the automated scripts to create the main page and the sequence-pages.

New page thoughts:

The Definitions no longer refer to anything on the front page, but if you move them to all the table pages, they will take up space there. Most of the current contributors are familiar with them, but new comers should be able to find them easily. If they are set up minimally at the top of the tables with a scroll like the Contributors' block, would it work?

I'm flip-flopping with whether the Navigation block is necessary. It does allow for a small area with access to all the bases, but access to all the bases is directly available just below that, even though that area is a little more expanded and if you want a specific type, it's an extra click.

If you do keep the Navigation block, maybe instead of the extra set of buttons under "Links and Statistics," the left column headers in the Navigation block could be active links.

[SIZE=7][COLOR=Red]New conjectures[/COLOR][/SIZE]


We now have three lines of research in our project :

1) Work on the occurrences of prime numbers in the sequences and work on the prime numbers that terminate the sequences (resumption of the data analysis planned for the summer of 2021).
2) Work on the cycles that complete sequences, according to the bases (analysis work planned for a later date, because we have too few cycles for the moment).
3) Work on the increasing beginnings of sequences ending in a trivial way : new research axis which will be discussed in this post.

This new line of research was not part of the original idea of ​​the project and was discovered by chance.
This also happened for axis 2).

In the first part (I), I propose conjectures and I comment on these conjectures.
In a second part (II), I explain how I proceeded to observe the behaviors which made it possible to state the conjectures. I present a data table.
In a third part (III), I make remarks and I ask more general questions.


[B][SIZE=5]I) Statement of new conjectures :[/SIZE][/B]


I decided to number the conjectures in the continuity of those presented in the [URL="https://www.mersenneforum.org/showthread.php?t=23612&page=41#447"]post #447[/URL].
So, we start here with the conjecture number (134).
The numbers we are talking about in this post are all integers.
The conjectures stated here concern sequences n^i which terminate trivially.
Reminder : This happens if n is a double of a square or if n and i have the same parity.
Preliminary remark : if the base is a prime number p, then s(n^p)<p.
For this reason, we only examine the growth of sequences from index 1.
We look at these sequences that must end trivially which first start growing from index 1 over one or more iterations.

Hope you find some interest in these new conjectures.
Some of these conjectures may already be known !

Some may also be invalidated in the future !

[B][U]Conjecture (134) :[/U][/B]
[I][B]If a basis b = p# is primorial (p prime > 7), then the sequence that starts with the integer b^14 is increasing from index 1 for a few iterations.[/B][/I]
Note 1 : In general, this does not seem to be the case with the other exponents, except exponent 8 (see conjecture 135).
Note 2 : We believe that if we compute the following larger primorial bases, the growth phenomenon will occur with other exponents. To check.
Note 3 : This conjecture is completed and replaced by [URL="https://www.mersenneforum.org/showpost.php?p=575400&postcount=1074"]conjecture (140)[/URL].

[B][U]Conjecture (135) :[/U][/B]
[I][B]If a basis b = p# is primorial (p prime > 29), then the sequence that starts with the integer b^8 is increasing from index 1 for a few iterations.[/B][/I]
Note 1 : In general, this does not seem to be the case with the other exponents, except exponent 14 (see conjecture 134).
Note 2 : The same as for conjecture (134).
Note 3 : This conjecture is completed and replaced by [URL="https://www.mersenneforum.org/showpost.php?p=575400&postcount=1074"]conjecture (140)[/URL].

[U][B]Conjecture (136) :[/B][/U]
[I][B]If a base b = (p#) / 2 is primorial without the factor 2 (p prime> 3), then some sequences of this base grow from index 1 for a few iterations.[/B][/I]
Note 1 : Until today (March 2021), we have only found three other odd bases for which this is also the case :
231 (3 * 7 * 11), 3003 (3 * 7 * 11 * 13) and 51051 (3 * 7 * 11 * 13 * 17),
to be seen as a primorial numbers without the factors 2 and 5 ?
Because 3003^5 and 51051^11 also have this property !
Note 2 : It is possible that this is just an illusion, maybe there are many other odd numbers that have the property ?
Note 3 : many of the exponents are prime numbers (especially 11 and 23) and not prime exponents are often equal to 7 * 5.

[U][B]Conjecture (137) :[/B][/U]
[I][B]Base 2 sequences starting with 2^(12 * k), 2^(40 * k), 2^(90 * k), 2^(140 * k), 2^(210 * k), 2^(220 * k), 2^(330 * k), are increasing from index 1 for a few iterations.[/B][/I]
Note 1 : This is not the case for the other exhibitors we have examined.
Note 2 : We believe that there must be other exponents of the form z * k (with z>330) which have this property.
Note 3 : We think that this phenomenon is related to the theorem which says that if p prime, s (p^i) is a factor of s (p^(i * m)) for every positive integer m, see [URL="https://www.mersenneforum.org/showthread.php?t=23612&page=43#466"]post #466[/URL].
This theorem ensures, for example, that exponents multiple of 12 have many prime factors in their decomposition (like 2^12 itself), which ensures them growth for a few iterations.
Because of this mechanism, this conjecture looks more like those of [URL="https://www.mersenneforum.org/showthread.php?t=23612&page=41#447"]post #447[/URL].


[B][SIZE=5]II) How to see these conjectures, with what data ?[/SIZE][/B]


To state these conjectures, it was necessary to present the data as clearly as possible, as below.
It looks very similar to the tables presented by Edwin, in the previous posts.
By looking at this data, anyone can discover their own conjectures.
Because it is certain that we missed things, perhaps even more spectacular or more general than what we present above.
It's your turn...

[U][B]Remark 1 :[/B][/U]
All bases of the form b = 2 * n^2 produce growth from index 1 only for even exponents.
Can we observe the growth for the bases of this form with odd exponents ?

[U][B]Remark 2 :[/B][/U]
For some even and odd bases, there seems to be a lot of sequences with the properties of growth from index 1.
For others, there seems to be none.
If we notice that many "big" bases have only one sequence having the property, keep in mind that we can not calculate a lot of sequences with big exponents for these "big" bases.
It is impossible today to formulate a conjecture specifying which even or odd bases would have the property of growth or not.
But we see the advantage of calculating at least up to index 2 all the sequences which have an exponent of the same parity as the bases.
And above all, we understand that it would be necessary to calculate further the bases less than 10 (3, 5, 6, 7) which do not have the property of growth, because they are the easiest to calculate with large exponents.
It is extremely curious that for the base 2 * 3 we have nothing while for 2 * 5, 2 * 7, 2 * 11, 2 * 13, 2 * 17 we have as many !
What about 2 * 19 and 2 * 23 and ... ?

[U][B]Remark 3 :[/B][/U]
One could write a multitude of conjectures similar to the conjecture (137) bearing on other bases.
For example, for base 10, we could write a conjecture like this :
[B][I]Base 10 sequences starting with 10^(36 * k), 10^(60 * k) are increasing from index 1 for a few iterations.[/I][/B]
And if we continued the calculations further with higher exponents, we would certainly add 10^(84 * k), 10^(90 * k) and 10^(96 * k) to our conjecture.
Ditto for bases 14, 20, 22, 26 ...
Everyone can observe for themselves what is happening for all these bases.
We did not find it necessary to formulate all these similar conjectures here.

[U][B]Remark 4 :[/B][/U]
Conjectures 134, 135, and 136 are baffling and seem of a fairly new kind, while Conjecture 137 seems to come close to what we already know.

[U][B]Remark 5 :[/B][/U]
We have failed to make a more general guess.
But there must be a lot of new things to note.
We must take a good look at this data and add more data to it !

I suggest you compile all of these conjectures, including the proved and disproved ones, onto a page (or pages) on your website for easy access. In particular, the link you provided in that post is irrelevant to me because I have a different number of posts per page, so I still have to search through the page list to find it, so having a single, stable link would be beneficial.

Excellent ! One more cycle !
This is our first cycle for base 439 !
