```Hi Seqfans,
I tried to research this and think the two sequences may be connectedwith this formula:1/((x(n)/A161527(n)/A038110(n+1))+1)=A161527(n)/A060753(n+1),
where x={1,1,16,64,256,36864,9437184,...}
ie for n =3:
1/((16/A161527(3)/A038110(4))+1)=A161527(3)/A060753(4)=1/((16/11/4)+1)=11/15.

For n=4:
1/((64/A161527(4)/A038110(5))+1)=A161527(4)/A060753(5)=1/((64/27/8)+1)=27/35.Sequence x is actually interesting so I think it is worth submitting sequence x to OEIS and merging the two sequences A161527 and A254196.cheers,Jamie

Michel, good catch! No one seems to have noticed this before. But the
corresponding denominators
of the two sequences are different, A038110 vs A060753. I've added more
cross-references
between these sequences.

I think someone should do some research here and figure our exactly what is
going on before we merge them. I've added this to my list of "sequences
that need work".

Best regards
Neil
