%N Primitive numbers n such that 1/n is in the Cantor set.
%C Sequence A121153 gives the n such that 1/n is in the Cantor set. Most of those n are 3 times a smaller number in that sequence. This sequence has only those terms in A121153 that are not 3 times a smaller number in the sequence. Note that A076270 is a subsequence.
