oddly specific

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

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

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

No, you can't have a group of zero, so the counter doesn't need to waste a position counting zero.
Tell that to the Castlevania 2 devs. https://lemmy.ml/comment/19720906

Powers of two are the roundest of numbers.
Much later in my career I came to appreciate the beauty of this system and the link with hexadecimal. I had to debug a network transmitted CRC that was endian flipped and in that process learned that in the Galois Field of two, 1+1=0 which feels delightfully nonsensical to a luddite.

A previous version of this article said it was "not clear why WhatsApp settled on the oddly specific number." A number of readers have since noted that 256 is one of the most important numbers in computing, since it refers to the number of variations that can be represented by eight switches that have two positions - eight bits, or a byte.
Lol, weird way to say that 256 is a power of two, and computers operate in base two.
Their definition is a lot better.

I can no longer tell if these are bits. 🫠

Shout out to Castlevania II, where you can hold anywhere from 0 to 256 laurels. Yes, you read that right -- 256, not 255. I inspected RAM to double check. It's a 16-bit word on an 8-bit system with a maximum value of
0x100. They could have used 8 bits instead of 16. But no, they really did choose this arbitrary number.how can you hold 0 laurels? that's different from not having laurels?

If this is about a counter for users in the chat, sure. But if this is an array of users indexed by an 8-bit number, then it will fit 256 slots with the first slot being numbered 0.
this guy indexes

the number of laurels in your inventory is stored as an integer from 0 to 256.

They just do it to look cool in front of their developer friends.
Pretty much this...
Once upon a time, sure, you might have used an 8 bit char to store an array index and incur a 256 limit for actual reasons....
But nowadays, you do it because 256 is a "cool techy limit". Developers are almost all dealing with at least 32 bit values, and the actual constraints driving smaller values generally have nothing to do with some power of two limitation.
-
Maybe they keep some other data in the same space using bitmask?
Even if true, 256 would be a waste of the range. 255 would make sense if trying to stay in one byte, using a whole different data type to get one extra bit just to hold 256 instead of saying "screw it, let's go to 511" even while using other bits.
It's just a very weird thing to do to pick 256 as a value limit back in those days (also oddly specific now, but for different reasons)

They're not round, they're square!

ITT: People who have never done low level networking.
Edit: Without some absolutely crazy hacks, the smallest amount of data you can really transfer or compute on is one byte. 256 requires one byte, 257 requires you to DOUBLE the data used to 2 bytes. Multiply this by whatever data they send and the problem remains the same.
This is the kind of thing that comes up a lot designing custom protocols.
My experience is that a limit of 256 means they probably are willing to allocate up to 24 bits to send the value over the network:
0x323536
People seem to love to pass around their numbers as JSON or similar.
-
They're not round, they're square!
Only every other one...

Numbers guy here, I can confirm 256 is an evenly specific number, and not an oddly specific number.
But is it Numberwang, Mr. Numbers Guy?

Well done! -
