EXAMPLE
The initial values of b(0), b(1), ... are:
b(0) = 0
b(1) = [1, 1]
b(2) = [2, 3]
b(3) = [2, 5]
b(4) = [2, 7]
b(5) = [2, 9]
b(6) = [2, 11]
b(7) = [3, 14]
b(8) = [3, 17]
b(9) = [3, 20]
b(10) = [3, 23]
b(11) = [3, 26]
b(12) = [3, 29]
...
The second terms give the present sequence.
The sequence of values of the first terms b(i)[1] for i >= 1 consists of 1 (once), 2 (5 times), 3 (30 times), 4 (225 times), 5 (1800 times), 6 (15000 times), ... (see A318920).
