If n = D010^0 + D110^1 + D210^2 + .. + Dk10^k define f(n) = D00^10 + D11^10 + D22^10 + .. + Dkk^10 (e.g. if n = 421 then f(n) = 42^10 + 21^10 + 1*0^10 = 4098). Sequence gives values of n such that f(n) is divisible by n.

If n = D0*10^0 + D1*10^1 + D2*10^2 + .. + Dk*10^k define f(n) = D0*0^10 + D1*1^10 + D2*2^10 + .. + Dk*k^10 (e.g. if n = 421 then f(n) = 4*2^10 + 2*1^10 + 1*0^10 = 4098). Sequence gives values of n such that f(n) is divisible by n.
