COMMENTS
The digits of this sequence follow the pattern odd/even/odd/even... as do the digits of the sequence A307129.
A307129 and this sequence need a lot of backtracking to be computed; this means that the last few terms of A307129 and of this sequence might evolve. However, the first 100 terms proposed here seem accurate.
