Number of subsets of {1..n} with all distinct lengths of maximal runs (increasing by 1). A384175

Sequence of pairwise relatively prime numbers of class P₅ (see comment in A275246). A275249

a(n) = (n+2)*a(n-1) + a(n-2), with a(0)=0, a(1)=1. A58308

Triangle read by rows. Let S(k) be the sequence defined by F(0)=0, F(1)=1, F(n-1) + (n+k)*F(n) = F(n+1). E.g. S(0) = 0, 1, 1, 3, 10, 43, 225, 1393, 9976, 81201, ... Then S(0), S(1), S(2), ... are written vertically, next to each other, with the initial term of each on the next row down. A102472

Triangle read by rows. Let S(k) be the sequence defined by F(0)=0, F(1)=1, F(n-1) + (n+k)*F(n) = F(n+1). E.g. S(0) = 0,1,1,3,10,43,225,1393,9976,81201, ... Then S(0), S(1), S(2), ... are written next to each other, vertically, with the initial term of each on the next row down. The order of the terms in the rows are then reversed. A102473
