Number of idempotent 4 X 4 0..n matrices of rank 1. A224526

Degrees of primitive irreducible trinomials: n such that 2ⁿ - 1 is a Mersenne prime and xⁿ + x^k + 1 is a primitive irreducible polynomial over GF(2) for some k with 0 < k < n. A1153

G.f. A(x) satisfies A(x)⁵ = BINOMIAL(A(x)⁴); that is, the binomial transform of the coefficients in A(x)⁴ yields the coefficients in A(x)⁵. A90356
