COMMENTS
A sequence q of length k is strictly pandigital if it is a permutation of {1,2,...,k}. It is polydivisible if Sum_{i = 1...m} 10^(m - i) * q_i is a multiple of m for all 1 <= m <= k.
EXAMPLE
Sequence of sets of n-digit numbers that are weakly polydivisible and strictly pandigital is (with A = 10):
{0}
{1}
{12}
{123,321}
