a(n) = n·sigma2(n). A328259
a(n) = 6·a(n-5) - a(n-10) + 98 with a(0)=0, a(1)=11, a(2)=35, a(3)=56, a(4)=104, a(5)=147, a(6)=204, a(7)=336, a(8)=455, a(9)=731. A118554
Triangle P, read by rows, that satisfies [P7](n,k) = P(n+1,k+1) for n>=k>=0, also [P7·m](n,k) = [Pm](n+1,k+1) for all m, where [Pm](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. A111830
Number of partitions of 6·7n into powers of 7, also equals column 1 of triangle A111830, which shifts columns left and up under matrix 7th power. A111831
