EXAMPLE

This sequence may be redrawn as an array with rows of lengths 1, 2, 4, 8, 16, ...:
1,
1, 5,
1, 7, 3, 15,
1, 7, 6, 30, 5, 26, 7, 35,
1, 7, 6, 30, 8, 48, 15, 71, 7, 33, 18, 86, 14, 70, 17, 81,
1, 7, 6, 30, 8, 48, 17, 81, 9, 50, 29, 141, 25, 131, 30, 152, 6, 27, 20, 96, 25, 147, 44, 208, 17, 81, 42, 198, 32, 158, 37, 173,
...
See A322048 for the final element of these rows; see A322049 for the sequence to which the rows converge, with additional formulas for the nth element of each (sufficiently long) row.  M. F. Hasler, Dec 18 2018
