Dear seqfans,

I have just submitted the following sequence:

%I A178253
%S A178253 4,2,4,2,2,4,4,2,2,2,2,4
%N A178253 a(n) is the least number m such that (A001969(n))^m is in A000069 
%F A178253 If k=A001969(n)=2^m*A001969(s), where A001969(s) is odd, then a(n)=a(s). 
%Y A178253 A000069 A001969 
%K A178253 nonn
%O A178253 1,1
%A A178253 Vladimir Shevelev (shevelev(AT)bgu.ac.il), May 24 2010

Can anyone to extend it?

Best regards,

 Shevelev Vladimir‎
