1,2

Conjectured to be a permutation of the natural numbers.

It would be nice to have a formula or recurrence. Note that the first row of the analogous array corresponding to the Wythoff game, A004482, does have a simple formula.

See A295563 for much more about this sequence. - N. J. A. Sloane, Mar 10 2019
