Comments

If m > 0 belongs to the sequence, then A054429(m) also belongs to the sequence; this accounts for the symmetries visible in the binary plot of the sequence (see Links section).

For any k >= 0 and any e in {-1, 0, +1}, 2^k + e belongs to the sequence.

Examples

			A187769(53) = 53, so 53 belongs to the sequence.
