Wikipedian Sloanians
I've been wanting to add a sequence to OEIS, but everything I can think of has already been added. So far I know of at least one other Wikipedian who has successfully sent in a new sequence to OEIS. I wonder if there are more. PrimeFan 22:52, 20 Jul 2004 (UTC)


 * I'm sure there are other Wikipedians besides myself adding sequences to OEIS. But I know what you mean when you say "everything I can think of has already been added". I was thinking of adding 21, 36, 55, 60... but even that had already been added, and in the early days of OEIS, too! Del arte 20:11, 4 Aug 2004 (UTC)


 * You're meant to submit sequences you come across in another connection, not to make up sequences for the sake of inclusion . Joseph Myers 19:01, 2 Dec 2004 (UTC)


 * Did it ever occur to you that Wikipedians who edit articles about mathematics might actually research mathematics? Did it occur to you that being a contributor to the OEIS would make a Wikipedian more credible on the subject? Del arte 15:14, 6 Jan 2005 (UTC)


 * I'd consider that fairly self-evident; after all, I'm pointing to a FAQ saying the sequences you enter should be those that show up in your research. OEIS is actually very inclusionist in practice, but some sequences are still so contrived that they get rejected and NJAS does try to discourage, on the FAQ and occasionally on the seqfan list, just submitting made up sequences definitions unless they are very good.  Being a researcher doesn't make one immune to temptation to make up sequences, so a pointer to the OEIS policy seemed worthwhile.  Although no longer active in research myself, I have in OEIS both sequences arising from published research (A079102-A079106), sequences from less formal or more recreational studies and other sequences arising from extensions of existing sequences or requests by NJAS or on seqfan.  (And even very contrived sequences can be of use in OEIS where they provide the solution to puzzles.) Joseph Myers 12:50, 7 Jan 2005 (UTC)


 * I can only speak for myself, but I thought the way you pointed to that FAQ insinuated that User:Del arte and I sit around making up sequences just so our names can appear in the OEIS. I felt slightly offended by that. If I ever send in a sequence to the OEIS, you can be sure it will be something groundbreaking, like the sequence of odd perfect numbers. But even without direct effort on my part, I have been mentioned in the OEIS, by screen name. PrimeFan 21:16, 7 Jan 2005 (UTC)

List of Wikipedians who contribute to OEIS
If you are a Wikipedian who has contributed sequences to OEIS, rank yourself into the list below by the number of sequences you've added.


 * 1) User:Joseph_Myers Fifty-two sequences, A070764, A070765, A070766, A070767, A070768, A071332, A071333, A071334, A073733, A075198, A075199, A075200, A075201, A075202, A075203, A075204, A075205, A075206, A075207, A075208, A075209, A075210, A075211, A075212, A075213, A075214, A075215, A075216, A075217, A075218, A075219, A075220, A075221, A075222, A075223, A075224, A075678, A075679, A079102, A079103, A079104, A079105, A079106, A089454, A089455, A089456, A089457, A089458, A093989, A093990, A093991, A093992, plus contributions and extensions to other sequences.
 * 2) User:Del arte Ten sequences, A095714, k such that 10^k - 9 is a prime; A095995, Primes of the form 100n - 1, A096064, Let p(k) = k-th prime; sequence gives primes q of the form q = k*p(k) + 1 for some k, A096065 Let p(k) = k-th prime; sequence gives primes q of the form q = k*p(k) - 1 for some k, A096207 Primes expressible as a sum of even indexed primes, A096208 Primes expressible as a sum of odd indexed primes, A096333 Prime numbers that are two less than an odd, prime-indexed triangular number or one more than an even, prime-indexed triangular number; A096234 Base 10 "digit addition generators" (zeroes in the sequence are self numbers); A100700 nth Fibonacci number minus nth prime number; A097942 highly totient numbers; plus comments and programs. I've also added, at Neil Sloane's request, a few sequences from PrimeFan's Listing of Esoteric Integer Sequences, which I'm not counting in this total.
 * 3) User:Robert Happelberg Four sequences, A100669 Zeros of the Mertens function that are also prime; A101648 Atomic numbers of the metalloids or semimetals on the periodic table; A101647 Atomic numbers of the nonmetals in the periodic table; A101649 Atomic numbers of the poor metals on the periodic table. Bob Happ gets extra credit here for putting links to Wikipedia in three of the four sequences he's sent in.

PrimeFan has indirectly contributed to the OEIS. Sloane himself found many of the sequences in his Listing of Esoteric Integer Sequences to be more interesting than esoteric.

NPOV
The statement in the lead section "It is considered one of the major resources in mathematics." is POV unless attributed to a source. Besides, is that a fact, or is that just something someone interested in integer sequences would say? - Taxman 15:34, Dec 31, 2004 (UTC)
