Index entries for sequences that are permutations of the natural numbers

Formula

Row 1, A035513, is the 4th-order Zeckendorf basis, b(1), b(2), b(3), .... Every positive integer has a unique 4th-order Zeckendorf representation b(i(1)) + b(i(2)) + ... + b(i(n)), where |i(h) - i(j)| >= 4 for distinct h and j.

Example

Northwest corner:
   1   2   3   4   5   7 10 14 19 26 36 50 69 ...
   6   8   9  11  12  13 ...
  25  32  34  35  42  44 ...
  94 120 127 129 130 156 ...
For example, 32 = 26 + 5 + 1 has 3 terms, so 32 is in row 3.
