Base 4 is covered by base 2 (since 4^n = 2^(2n)). Similarly, any perfect power will be covered by its base. So, 4,8,16,32,36,etc... need not be searched.

EDIT:- I'll work on base-12 to 50,000. I'll sieve base-18 to 100,000 but not sure how far I'm willing to test. Will know further once I'm done with base-12.
