73 is the 21st prime number.
Its mirror, 37, is the 12th.
And ITS mirror, 21, is the product of multiplying -- hang on to your hats -- 7 and 3
In binary, 73 is a palindrome, 1001001,
Which backwards is 1001001.

Wow, thanks for pointing that out.

New question! Better for /sci/

Given a binary number of length x digits what is the probability that it will be a palindrome?

>> No.2192864

>>2192850
sqrt(x)?

>> No.2192872

>>2192850
I'd be more interested if 73 is unique in that there is no other number which is the nth prime, whose mirror is the mth prime, such that n and m are mirrors.

>> No.2192873

>>2192850

I starting thinking about this when this dude posted, and started to think about floor functions and stuff. But as it turns out, exactly half of all binary numbers are palindromes.

What other sitcom brings up numerical patterns worthy of discussion? Anyone hating on this show is unworthy to call himself a nerd.

That only works if you think in base ten sets

>> No.2192967

>>2192947
True, the concept of a numbers "mirror" is a base-dependent concept, not intrinsic to the number, so maybe that makes it a little less interesting.

All numbers are interesting. If some numbers were uninteresting, there would be a smallest uninteresting number. But then it would be interesting. This creates a paradox.
