%N a(n) = A253563(A003714(n)).

%C After the initial terms 1, 2 and 4, all other terms can be inductively generated by applying any finite composition-combination of A253560 and A253550 to 4, but with such a restriction that A253550 may not be applied twice in succession.

%C A permutation of A055932.
