[QUOTE=cheesehead]But, Mally, I wrote 16421225 without commas. You might check earlier in this thread for somewhat similar numbers. Not all of them were proposed for purely arithmetic reasons. :-)[/QUOTE]
Ho, Ho, :yawn: That's being unfair Cheesehead ! Rather sadistic I would say!
When I was last in New York I had three volumes of Directory, Two of yellow pages and one on entertainment all stacked in my suite for ready reference.
Besides the AT&T had a service to find numbers not listed and ex directory.
To pick any number from there at random would be tom foolery to say the least.

Whereas certain numbers could be interesting to remember which were not with a mathematical connotation it could have been limited to 4 or 5 digits!

In other words I give up on your number and look forward to some words of wisdom from you which when broken into parts as I have done, its an aid to my memory and you will be happy to know that Ill remember it to my dying day as Cheeseboard's number.
If its not mathematical in any single way I will put it down as the most uninteresting number that had come my way.

In keeping in the same spirit I will disclose the number I gave namely 104729 as the 10,000 prime taken in order. If you are not familiar with a unit we use it is written or spoken as 1 lakh 4 thousand and 29. There are other ways in which this number can be expressed too but its irrelevant to my point.
Would you call it non mathematical ?

I hope patiently for your rendition of your number with bated breath. :whistle:

Christmas Day 1642...?

Isaac Newton's Birthday.

nice one, Cheeseboard


I'm still puzzling over 297: I'm sure I've met it before. Somewhere.


a quickie for mally: 11,187 (!)

:smile: Thank you both. How could I miss it as it worth noting.
Lets remember Sir I Newton this Xmas amidst our fun and frolic.
Thank you Richard (hey, you are both Richards) for a brain tickler in 11,187.
Its not in the Penguin Dict. nor in the other URL given in this thread. All I could do is this 11,187 = 3^2 * 11 * 113 and all No's are primes.
Moving on to greener pastures I found 113 - permutable prime.
Google pp and you get Prime Curios! 113.
Click on that and a whole mind blowing list of properties of 113 follows.

297 is a Kaprekar number. I met the man who was all brain and puny body.

My number 104729 is difficult and not expected so I give a hint
Its the nth prime so what is n?

errr sorry: 11,187 wasn't meant very seriously, its just that its in the news (in the UK) today: think 99.94


Of course that doesn't stop 11,187 being special for a valid mathematical reason, if we look hard enough...

:surrender Hey Richard: What's new on the news today? Give me a better tip. In My Penguin Dict. your number 11,187 is one more than its entry for 11,186.
The other URL had only numbers up to 9999. So I have to get back to paper and pencil if at all it has some deeper meaning ?
Well I dont mind as I follow Pythagoras "All is number"

the second ed doesn't list 11,186, or indeed anything near 11,187. But I repeat, the very short-term significance of 11,187 [B]is nothing to do with mathematics[/B]. And I expect the significance that it currently enjoys will expire tomorrow. not sure if thats a good clue or not.

104,729 is the 10,000th prime.

-1 + 0 + 1 = my IQ! (Also works with multiplication.)

or

e^(i pi)+1 =0

:surprised
Flatlander: Is the number 40,075 mathematical, historical, or statistical ?

Unless the number has a mathematical property its not worth considering
IMO in this thread. Exceptions should be important historical dates such as given by Cheesehead,(Newton's birthday) or statistical info which we could value of important numbers stretching to decimals like Phi = 1.6180339 will be welcome.

A number like Lara's record breaking spell is not worth bothering and a waste of precious time. These numbers are grass today and hay tomorrow only meant for the kiln or animal feed.
Could you please recommend some good books on numbers which have math properties ?
Thank you
Mally :coffee:
