(In reply to re(4): Not a Solution by Richard)

Do you think there is a unique solution to the problem? Might there be a unique solution in one base and many solutions in another? I started my program for base ten before going to bed - so I don't know how long it took. Since my program was a brute force method (with a few assumptions), increasing the base value would increase the run time dramatically.
