%N Permutation of nonnegative integers: a(n) = A057889(A263273(n)).
%C Perform an adjusted reverse of n in base 3, followed by another adjusted reverse in base 2. "Adjusted reverse" here means a digit-reversing operation where the suffix of trailing zeros (in the base in question) stays as it is at the right side, and only the section from the most significant digit to the least significant nonzero digit is reversed.

%F Other identities. For all n >= 0:
%F A000035(a(n)) = A000035(n). [This permutation preserves the parity of n.]
