OEIS Sequences

Number of compositions (ordered partitions) of n into tetrahedral (or triangular pyramidal) numbers (A000292). A282582

Triangle T(n,k), n>=0, 0<=k<=n, read by rows: row n is the inverse binomial transform of the n-th row of array A255961, which has the Euler transform of (j->j·k) in column k. A257673

Conjecturally, number of infinitely-recurring prime patterns on n consecutive integers. A23192

Expansion of e.g.f. (1/x) * Series_Reversion( x·exp(-x * (1 + x)²) / (1 + x)² ). A380781

Numbers generated by recursive procedure a(n) = nozero(a(n-1) * 3), in which the function nozero(x) removes all zeros from x, starting with a(1) = 1. A243845
