%N a(n) is the smallest number k such that k * A002202(n) is not a term of A000010.
%C a(n) is an odd number >= 3.
%C a(1) * A002202(1) = 3 is the only value not a term of the sequence A005277.
%C Terms of this sequence map terms of A002202 to terms of A005277 and the image of these mappings is a subset of A005277. For example, between A005277(1) = 14 and A005277(5) = 50, there is no mapping.
%e 3 is a term because 3 * A002202(1) = 3 and 3 is not a term of A000010.
%e 7 is a term because 7 * A002202(2) = 14 and 14 is not a term of A000010.
