A prime number "game of life": can floor(y*p#) always be prime?

[mart_r]

An old pet project of mine, revamped.

If it's in any way possible I would like to turn this into a fully-fledged arXiv paper, so any suggestion on how to proceed with the work in the attachment is highly appreciated.

"In this paper, the author discusses the existence of a real number y such that q = \(\lfloor\)p#*y\(\rfloor\) is a prime number for every p \(\geq\) 2."

You may berate me for any technical or formal errors or glitches, obsolete or false statements, inappropriate verbiage or lack thereof, or for opening a new thread (in my defense: this time with a fitting title, and gravedigging is considered rude just as well) - but remember that beraten in German means to discuss or give advice.

But the ensuing discussion can also be a gift.

It would be nice to see a version of table 7 with primes removed if their branch has terminated in a future iteration(numbers should be monotone increasing in this case).

It is a shame that the branching rate seems to increase as the numbers get larger.

I've already had an idea that leads into this direction. A version of the table including the monotonely increasing number of surviving primes shouldn't pose much of a problem to me.

It would definitely be more of a discovery if there was a unique solution for a surviving branch.

Here's an updated version of Table 7, currently at level 1723. (Preliminary, as you can tell n* is backtracked from the currently calculated stage, not stage 294 as mentioned in the PDF.)
I let one laptop crunch the numbers en passant, and plan to reach level 1931 by mid June. I wouldn't go that far if it wasn't just to fill the rightmost columns.
Plus I'd also like to find a prime with ten descendants (cf. page 18 of PDF in OP).

Here's the updated table 7 for you, including the Pari program where I previously forgot to adjust the variable names to the text.

And here's a decuplet too: (193,057^th prime of s = 289) * 1,889 + {220, 238, 378, 624, 934, 1048, 1414, 1612, 1678, 1750}
where the 193,057^th prime of s = 289 is

Yay! *Throws up a single confetti* Or is that called a confetto?
Oh! Look at how the number starts off... wait... contfrac((log(a)/log(10)) = 796; 2, 41939, 2, 101, 1, 7, ... - nice!

Now at p=1931... but, you know, the year 1931 was not an especially nice one in terms of history. I'll continue to crunch the numbers down. I am unstoppable!!

You know, it only recently occured to me that those numbers have a subtle crude sense of humour, looking at the point where the first sextuplet appears.

And that was me relying too much on German grammar, which makes it funny in a non-intentional way - and because I'm not able to edit, I just make a new post.
It should read *Throws a single confetti in the air*
See, now it's not funny anymore

It's a shame that extending the search made so little difference lower down. From 599 to 797 the difference is only 1. I was hoping that more could be eliminated. Maybe some more could be if the easiest targets are attacked rather than everything.
