A Pandigital Programming Challenge
based on Amarnath Murthy's (email) sequence A061604.

A pandigital number is a number containing all ten digits from 0 to 9.
For the sake of this topic we allow multiplicity of the digits.
Amarnath Murthy submitted integer sequence A061604 to Sloane's
database in May 2001, displaying the smallest pandigital multiples of n.

91137174211023456789
101234567891234567890
11etc.etc.

As you can see all the pandigitals in the right column are ten (10) digits
long for these first few values of n. What I like to ask you now is to find
the smallest set (n,m) so that n*m is a pandigital number of at least
eleven (11) digits.
I hope you enjoy this programming challenge !
