EXAMPLE
The 2nd row [4, 5, 7, 6] gives the number of iterations of -k/5 (the first element is not counted):
k=1 => -1/5 ->2/5 -> 1/5 -> 8/5 -> 4/5 with 4 iterations;
k=2 => -2/5 -> -1/5 -> 2/5 -> 1/5 -> 8/5 -> 4/5 with 5 iterations;
k=3 => -3/5 -> -4/5 -> -2/5 -> -1/5 -> 2/5 -> 1/5 -> 8/5 -> 4/5 with 7 iterations;
k=4 => -4/5 -> -2/5 -> -1/5 -> 2/5 -> 1/5 -> 8/5 -> 4/5 with 6 iterations.
The array starts:
[0];
[1, 2];
[4, 5, 7, 6];
[9, 10, 11, 11, 13, 12];
[4, 5, 1, 6, 3, 2, 4, 7];
