FORMULA
| Row 1, A035513, is the 4rd 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.
