Bases associated with A103662. [Corrected by M. F. Hasler, Mar 09 2014]
Zero values are conjectural. a(40) was checked up to 10^9 by Joshua Zucker. All other zero values were checked up to 10^5 by David Wasserman.
EXAMPLE
a(10) = 5 because 5^10 is the smallest 10th power containing no zero in its decimal representation (2^10 = 1024, 3^10 = 59049, 4^10 = 1048576).
CROSSREFS
Cf. A103662 = smallest power x^n with integer x>1 that has no digit 0 in its decimal representation.
