#32What to do if I've come up with an easily explainable number sequence that's not defined in the OEIS?
It's a simple algorithm that's easy to perform with a deck of cards

#33Well, does the Encyclopedia knows what comes after 1,2,4,8,16? Hint: if you follow the Mathologer, you would know that there is a number different from 32…
For a sequence of n numbers, fit an n-1 degree polynomial on (0, v_0), (1, v_1), ..., and compute for n. Doesn't even have to a polynomial. Any independent function base will do, I suppose. And who can contradict you?
Doesn't really matter what "mathologer" thinks the next number is.

There are an infinity of possible sequences you could write down. The ones in OEIS are ones where there's relevance to it in terms of other sequences or other mathematical ideas that make them useful to describe.

You submit it to OEIS and it may be added.

#36The following are real examples of submissions that were rejected: A-numbers of sequences contributed by [your name] (however, this might be appropriate on your OEIS Wiki user page). Experience points required for a Pokemon in the "erratic" experience group to be of level n. The year 10^n decimal digits of pi were first computed (Not well-defined!) Primes of the form n^3 + 2 n^2 + 37 n + 73. Non-trivial circulation i…
> Concatenate a semiprime with a Fibonacci number to obtain a palindrome with at least two distinct digits.
For some reason, the thought that someone worked on this makes me very happy :)

#37That analogy about the FBI fingerprint database is one of the most tortured metaphors I've ever heard.
The FBI would like to remind you that officially it's a "waterboarded" metaphor.

#38I keep on meaning to finish a redesign of the oeis site that I started a few months ago[0]. I've only spent a day on it so far, but I'm hoping it makes the site far more approachable to new comers. [0] https://oeis.femto.dev/
I really like what you did, great work! Please post it whenever you feel it's ready. I'd love to see the code too.

Some feedback: it lacks a search button. I mean, you can type a sequence, but have to hit the enter key to search. I'd expect at least some mouse-pressable button to be there that searches too (either the magnifying glass that's already there, or a button labeled "search"). You may say that "it's good enough you can press enter", however the site starts out already showing you the digit sequence "1, 2, 3, 6, 11" so y…
This was incredible feedback, thanks so much for taking the time to write it out. I've implemented 2, 3 and 4. You can now directly link to pages[0] and it'll auto-expand all boxes. The icons are intended to show whether the sequence has a code submission attached. There's now a popover attached to them to explain this.
1 will take some design work, and I've only got an hour or so to work on it now. I definitely agree however that a 'submit' button on a search is essential.

Wow thanks for implementing all those improvements!
