OEIS Sequences

Numbers n such that Bernoulli number Bn has denominator 690. A272186
Start with any initial string of n numbers s(1), ..., s(n), with s(1) = 2, other s(i)'s = 2 or 3 (so there are 2n-1 starting strings). The rule for extending the string is this as follows: To get s(n+1), write the string s(1)s(2)...s(n) as xyk for words·and y (where y has positive length) and k is maximized, i.e., k = the maximal number of repeating blocks at the end of the sequence. Then a(n) = number of starting strings for which k > 1. A93370
Numbers that are the sum of nine fourth powers in nine or more ways. A345593
Numbers that are the sum of nine fourth powers in exactly nine ways. A345851
a(n) = 2n - A122536(n). A121880
Total number of parts coprime to n in the partitions of n into 9 parts. A363327
Number of partitions p of n such that 2*(number of even numbers in p) < (number of odd numbers in p). A241651
Series for first parallel moment of hexagonal lattice. A6736
Series for radius of gyration for lattice animals on square lattice. A56261
Numbers k such that 10k + 2·Rk + 5 is prime, where Rk = 11...1 is the repunit (A002275) of length k. A102930
