%N A298607 Powers of 2 with the digit '0' in their decimal expansion.
%C A298607 The complement, A238938, is conjectured to be finite. Furthermore, Khovanova (see link) believes 2^86 = 77371252455336267181195264 is the largest power of 2 not in this sequence.

%e A298607 2^12 = 4096 contains one 0 in its decimal representation, hence 4096 is in the sequence.
%e A298607 2^13 = 8192 contains no 0's and is thus not in the sequence.
