OEIS Sequences

Square of lower triangular matrix of A056857 (successive equalities in set partitions of n). A78937

Triangle T(n,m,p,q) = (p^n-k*q^k + p^k*q^n-k)*(StirlingS1(n, k) + StirlingS1(n, n-k)) with p=2 and q=1, read by rows. A154913

Terms of A319928 that are congruent to 4 modulo 8: Numbers k == 4 (mod 8) such that there is no other m such that (Z/mZ)* is isomorphic to (Z/kZ)*, where (Z/kZ)* is the multiplicative group of integers modulo k. A372755

Primes congruent to 1 mod 6 generated recursively. Initial prime is 7. The next term is p(n) = Min_{p is prime; p divides 4Q²+3; p mod 6 = 1}, where Q is the product of previous entries of the sequence. A57204
