%N Index of first occurrence of n in A033093 (or 0 if not present).

%C Conjecture that the sequence contains no zeros; that is, A033093 is onto the nonnegative integers. Note that most of the values in the sequence are highly divisible, as would expected. a(7) appears to be the last odd value.

%e a(7)=27 because A033093(27)=7 and no smaller n has A033093(n)=7.

%Y Cf. A033093.
