Comments

Similar to A053668, which does not exclude zero digits from the product. This is to the cubes A000578 as A218072 is to the squares A000290.

Examples

			a(4) = A007954(4^3) = product of digits of 64 = 6 * 4 = 24, since none of the digits is 0.
a(10) = product of nonzero digits of 1000 = 1.
