Minimum number k for which the digital sum of k·n is 6·n. A147826

A new general triangle sequence based on the Eulerian form in three parts:m=2; t0(n,k)=If[n·k == 0, 1, Sum[(-1)^j Binomial[n + 1, j](k + 1 - j)ⁿ, {j, 0, k + 1}]] t(n,k,m)=If[n == 0, 1, ( m*(n - k) + 1)*t0(n - 1 + 1, k - 1) + (m·k + 1)*t0(n - 1 + 1, k) + m·k*(n - k)*t0(n - 2 + 1, k - 1)]. A157178
