OEIS Sequences

Number of strict compositions of n with no three consecutive parts in arithmetic progression. A325849

a(n) = a(n-1) + a(n-2) + a(n-3) - a(n-4); a(0)=0, a(1)=1, a(2)=1, a(3)=1. A116201

G.f. satisfies A(x) = 1/(1-x)³ + x·A(x)⁴. A364624

Partial sums of the ziggurat sequence A347186. A356351

a(n) = A060178(n) - A060015(n). A96596

For positive integers n, a multiset A of positive integers is called "n-good" if for any number 1 <= i <= n, we can find a submultiset B of A such that the sum of B is equal to i. a(n) is the number of minimal n-good multisets. A385675

a(n) = p(1)p(n) + p(2)p(n-1) + ... + p(k)p(n-k+1), where k = [ n/2 ], p = A000040, the primes. A25129
