A094607 Rectangular array T by antidiagonals: row n consists of the positive integers k for which there are exactly n sets of Fibonacci numbers whose sum is k.

1, 2, 3, 4, 5, 8, 7, 6, 11, 16, 12, 9, 13, 21, 24, 20, 10, 14, 26, 29, 37, 33, 15, 18, 27, 39, 42, 58, 54, 17, 19, 32, 40, 45, 66, 63, 88, 25, 22, 34, 47, 50, 76, 71, 97, 143, 28, 23, 35, 48, 60, 84, 79, 100, 105, 232, 41, 30, 43, 55, 61, 94, 92, 131, 113, 152, 376, 46, 31, 44

Comments

Row n gives the ranks of n in A000119 after the initial 1 is deleted. Every positive integer occurs exactly once in T; thus a is a permutation of the positive integers. Row 1 is A000071 except for initial terms. Column 1 is A013583.

Example

A northwest corner of T:
1 2 4 7 12
3 5 6 9 10
8 11 13 14 18
16 21 26 27 32
6 is in row 2 because there are exactly 2 sets of Fibonacci
numbers whose sum is 6. They are {1,5} and {1,2,3}.
