OEIS Sequences

Number of "ON" cells at n-th stage in simple 2-dimensional cellular automaton (same as A160410, but a(1) = 1, not 4). A160414
a(n) = 1·2 + 3·4 + 5·6 + 7·8 + 9·10 + 11·12 + 13·14 + ... + (up to n). A228958
a(n) = a(n-1) + a(m) for n >= 4, where m = 2p+1 + 2 - n and p is the unique integer such that 2p < n - 1 <= 2p+1, starting with a(1) = a(2) = 1 and a(3) = 3. A50033
Number of partitions of n such that the number of odd parts is a part. A240574
Triangle read by rows: T(n,k) number of arrangements of non-attacking rooks on an n X n right triangular board where the top rook is in row k (n >= 0, 1 <= k <= n+1). A259691
Triangular array giving number of bipartite graphs with n vertices, no isolated vertices and a distinguished bipartite block with k=1..n-1 vertices, up to isomorphism. A56152
Row 5 of A277710: Positions of 5's in A264977; positions of 10's in A277330. A277715
Start with the hexagonal tile of the Shield tiling and recursively apply the substitution rule. a(n) is the number of square tiles after n iterations. A298679
Number of partitions of n into parts not of the form 13k, 13k+4 or 13k-4. Also number of partitions with at most 3 parts of size 1 and differences between parts at distance 5 are greater than 1. A35952
Numbers of the form p·q*r where p,q,r are distinct odd palindromic primes (odd terms from A002385). A46405
