%N a(n) is the position in A342910 of the base-2 representation of n.

%C Conjecture: ((a(n)-2)/3) is a permutation of the nonnegative integers. See A342910 for a guide to related sequences.

%F a(n) == 2 (mod 3). - _Hugo Pfoertner_, Jun 02 2021

%e The positions of 1,2,3,4, in base 2 can be read from a list of the first 20 words in A342910: 0, 1, 00, 01, 10, 000, 001, 11, 010, 0000, 100, 0001, 011, 101, 0010, 00000, 110, 0100, 00001, 1000; so a(1) = 2, a(2) = 8.
