Dear  Jeremy,

I ask you also to extend a "dual" sequence:

%I A178307
%S A178307 3,3,2,3,3,2,3,4,2,3
%N A178307 Remove from A000069 powers of 2. Let b(n) be n-th term of the remain sequence. Then a(n) is the least number m such that (b(n))^m is in A001969 
%F A178307 If k=b(n)=2^m*b(s), where b(s) is odd, then a(n)=a(s). 
%Y A178307 A000069 A001969 A178253 
%K A178307 nonn
%O A178307 1,1

Regards,
Vladimir
