Numbers guy here, I can confirm 256 is an evenly specific number, and not an oddly specific number.

[–] banazir@lemmy.ml 4 points 1 day ago

But is it Numberwang, Mr. Numbers Guy?

[–] BlackXanthus@lemmy.world 1 points 23 hours ago

User name checks out

[–] BuboScandiacus@mander.xyz 19 points 2 days ago (2 children)

Oh you are the numbers guy ? Name every number

[–] kameecoding@lemmy.world 22 points 1 day ago (3 children)
[–] Valmond@lemmy.world 1 points 8 hours ago

What about -1 ?

[–] orochi02@feddit.org 1 points 1 day ago

So simple yet so effective as an answer

[–] prime_number_314159@lemmy.world 10 points 1 day ago (1 children)

I'm going for the boring but practical answer: {x | x ∈ A} and {x | x ∉ A}. Obviously the second set is doing the heavy lifting.

You should know your limits

As the numbers guy. Do you remember the name of the site that can tell you the what a given number is often associated with?

[–] prime_number_314159@lemmy.world 5 points 1 day ago (1 children)

Wikipedia often has disambiguation pages for numbers that may be helpful in a search like this (https://en.m.wikipedia.org/wiki/71).

WolframAlpha is good for identifying numerical properties of numbers (https://www.wolframalpha.com/input?i=71).

OEIS has a searchable set of sequences (https://oeis.org/search?q=71&language=english&go=Search)

I fear that none of these is what you're looking for, though. My attempts to find something that sounds like what you want mostly turned up resources on numerology, and at least one article apparently about how the meaning of numbers is radically different between cultures.

[–] qaz@lemmy.world 2 points 1 day ago

No that doesn't seem to be it. Thanks for trying anyway.

[–] JackbyDev@programming.dev 2 points 1 day ago

My brain is going to OEIS or angel numbers which are both like total opposites. Number theory or numerology, take your pick.

[–] chortle_tortle@mander.xyz 2 points 2 days ago (2 children)

Oh yeah well if you're some sort of numbers guy, answer me this: I think you're name is super cool, and makes me wonder, is there a largest prime you can make listing digits of pi starting from the beginning. There's gotta be infinite right?

[–] addie@feddit.uk 3 points 1 day ago (2 children)

Well, three is prime and pi starts with a three, therefore, even if there's larger primes, there is one which is the largest. QED.

[–] chortle_tortle@mander.xyz 0 points 1 day ago (1 children)

Unless there isn't one that's the largest because there are infinite primes.

[–] JackbyDev@programming.dev 1 points 1 day ago* (last edited 1 day ago) (2 children)

You started at zero and went to infinity. If you start at infinity and go to zero then the first prime you got is the largest. QED.

[–] chortle_tortle@mander.xyz 1 points 1 day ago (2 children)

I can no longer tell if these are bits. 🫠

(Thank you for the kindness of clarity ❤️ I may now be at peace.)

That's what she said...

Pi is suspected to be a normal number (though this has not been proven). If it is normal, it's likely that integers comprised of the first N digits of pi will be just as likely to be prime as comparable large integers. I suspect but cannot prove that there are infinitely many prime numbers whose digits are the first N digits of pi (with or without the leading 3).
