Number of partitions of 4·5ⁿ into powers of 5, also equals column 1 of triangle A111820, which shifts columns left and up under matrix 5th power. A111821

Triangle P, read by rows, that satisfies [P⁵](n,k) = P(n+1,k+1) for n>=k>=0, also [P^5·m](n,k) = [P^m](n+1,k+1) for all m, where [P^m](n,k) denotes the element at row n, column k, of the matrix power m of P, with P(0,k)=1 and P(k,k)=1 for all k>=0. A111820
