OEIS Sequences

G.f. A(x,y) satisfies: A( x - y·A(x,y)², y) = x + (1-y)*A(x,y)², where the coefficients T(n,k) of xⁿ*y^k form a triangle read by rows n>=1, for k=0..n-1. A277295

One-half the number of permutations of length n with exactly 2 rising or falling successions. A349

Triangle read by rows: T(n,k) is one-half the number of permutations of length n with exactly n-k rising or falling successions, for n >= 1, 1 <= k <= n. T(1,1) = 1 by convention. A10028

Triangle read by rows: T(n,k) = one-half number of permutations of length n with exactly k rising or falling successions, for n >= 1, 0 <= k <= n-1. T(1,0) = 1 by convention. A86856

a(1)=1. a(n) = a(n-1) + (sum of terms, from among terms a(1) through a(n-1), which are prime or 1). A104589

Central terms of triangle A277295 in even-indexed rows; a(n) = A277295(2·n,n-1). A277299
