OEIS Sequences

Sequence defined by the recurrence formula a(n+1)=sum(a(p)*a(n-p)+k,p=0..n)+l for n>=1, with here a(0)=1, a(1)=2, k=-2 and l=0. A177113

G.f. A(x) satisfies: A(x) = 1 - x * (1 - A(x/(1 + x)) / (1 + x)). A326829

10-gonal (or decagonal) numbers: a(n) = n*(4·n-3). A1107

a(n)-th and (a(n)+1)-st primes are the first pair of primes that differ by exactly 2n; a(n) = -1 if no such pair of primes exists. A38664

Number of one-sided triangulations of the disk; or flexagons of order n; or unlabeled plane trivalent trees (n-2 internal vertices, all of degree 3 and hence n leaves). A1683

Numbers whose base-16 expansion has no run of digits with length < 2. A33029

Every run of digits of n in base 16 has length 2. A33014

Array read by antidiagonals: T(n,k) = number of nonequivalent dissections of a polygon into n k-gons by nonintersecting diagonals up to rotation (k >= 3). A295224

Heinz numbers of integer partitions with as many even parts as odd parts and as many even conjugate parts as odd conjugate parts. A350946

Square array T(n,m) (n>=0, m>=0) read by antidiagonals downwards giving number of rooted triangulations of type [n,m] up to orientation-preserving isomorphisms. A262586
