I would like to see results for base 3.  I have a suspicion that there

Here are the results of my program for this problem.  Each line has 
numbers, "a b c" where c is an a-digit number equal to the sum of the 
powers of its digits (in the entries for 0 and 1, the value of b is


I'll leave the program running overnight and see how far it gets.  If
people want such computations for bases other than 10, I can readily 
those as well.
