DATA

1, 2, 4, 7, 3, 8, 5, 12, 14, 6, 16, 9, 21, 20, 10, 25, 11, 27, 28, 13, 33, 15, 37, 34, 17, 42, 18, 45, 19, 41, 48, 55, 22, 47, 23, 58, 24, 61, 54, 26, 66, 29, 60, 71, 30, 75, 31, 78, 32, 68, 81, 35, 87, 73, 36, 91, 79, 38, 96, 100, 39, 40, 102

COMMENTS

More precisely, A308021 is by definition injective but presently only conjectured to be a permutation. Until that property is proved, we define this sequence as a(n) = index of the n-th smallest term of A308021.
