%N A074211 Composites which use less than all of their digits in their prime factorization.
%C A074211 Prime numbers use all of their digits and an extra 1 (as a power) in their prime factorization. Thus this sequence can be defined as numbers which use a proper subset of their digits in their prime factorization. - _Tanya Khovanova_, Apr 20 2022
