Special numbers1. The special quality of the number 64 : it is both a perfect square and a percet cube. The smallest such number parat from zero and one . Let's call it it g3 for convenience. Character is who you are when no one is looking. #2 20061017 22:34:04
Re: Special numbersHow come g20 is more than g1000? Is g20 meant to have that second ^10 in there? Why did the vector cross the road? It wanted to be normal. #3 20061018 13:54:47

Re: Special numbersYes, exactly. g1000 *should* be a lot bigger than g20, but according to the 1st post, it's not.

Re: Special numbersThat was a mistake, mathsy, Admitted. Character is who you are when no one is looking. #6 20061019 20:02:59
Re: Special numbers
Nice post, thanks for providing the numbers #7 20061019 21:26:53
Re: Special numbersEach of these numbers is basically 2^{lowest common multiple of every number up to x}, which explains why it grows so quickly. Why did the vector cross the road? It wanted to be normal. #8 20061023 18:27:08
Re: Special numbersWith a hand held scientific calulator, 18 years ago. There are nearly 168 prime numbers from 1 to 1000. The highest powers of these numbers upto 1000 have to be multiplied. You get something close to 10^433. Therefore g1000 is roughly 10^10^433. Character is who you are when no one is looking. #9 20061230 09:28:30
Re: Special numbersganesh, you are well meaning and share an interest in the peculiarity possesed by certain numbers. But I take an interest in 0, the Alpha and Omega of all numbers. A number that alone signifies nothing but when merged with other numbers signifies much more. It is odd but true and we all know of these facts. Face it ganesh, 0 is awesome:D 0 can be nothing and something. 0 #10 20070120 22:01:13

Re: Special numbers
Counting things without the concept of 0 was never really a problem, I guess. Why on earth would you count nothing? Waste of time #12 20070121 16:20:25

Re: Special numbersRomans managed to do fairly well by using a system where the value of a number was determined by adding all of its digits, rather than using a base system. Why did the vector cross the road? It wanted to be normal. #14 20070122 10:33:50
Re: Special numbers
Haha, true, but why would you count 11!!!!!!! after 9? there's quite a difference between there two. (had to get back on ya ) #15 20070909 22:38:55
Re: Special numbersNooo!!! I shall be on leave until I say so... #16 20070910 04:21:25
