COMMENTS

As this is the sequence A246280 sorted into ascending order, this is also expected to grow roughly as a(n) ~ 2^(n-1) [In this sequence we use one-based indexing]. Please see comments in A246280.

The corresponding new values at A246271(a(n)) are: 0, 1, 2, 6, 7, 5, 3, 4, 11, 8, 10, 9, 15, 14, 13, 12, 17, 21, 20, 19, 18, 16, 24, 23, 22, ... (which is a permutation of nonnegative integers).
