OEIS Sequences

Positions of 2's in A264977; positions of 3's in A277330. A277712
Number of equivalence classes of binary sequences of primitive period n. A2730
Partition numbers rounded to nearest integer given by the Hardy-Ramanujan approximate formula. A50811
Triangle read by rows: T(m,n) (1 <= n < m) is the number of moves of an (m,n)-leaper (a generalization of a chess knight) until it can no longer move, starting on a board with squares spirally numbered from 1. Each move is to the lowest-numbered unvisited square. T(m,n) = -1 if the path never terminates. A323749
Numbers which are the sum of two squared primes in exactly three ways (ignoring order). A226562
Numbers k that are the product of four distinct primes such that x2+y2 = k has integer solutions. A248712
Number of n-step spirals on hexagonal lattice. A6777
Numbers that can be represented as a sum of two distinct nontrivial prime powers in three or more ways. A225104
Number of primitive (period n) step cyclic shifted sequences using exactly two different symbols. A56424
Successive records of function f(x) = log(abs(π(x) - R(x)))/log(x) where π(x) is the number of primes <= x and R(x) is Riemann's prime counting function. A353055
