COMMENTS

1. Every row satisfies the Fibonacci recurrence: x(n)=x(n-1)+x(n-2).

2. Row n of the Wythoff Array (A035513) is a tail of row n of A165357.

3. Every (a,b) having a>b>=0 occurs exactly once.

4. Every (c,d) having 0<=c<=d occurs exactly once.

FORMULA

Row n is obtained from row n of the Wythoff array (A035513) by applying

reverse Fibonacci recurrence until reaching a pair (a,b) having a>b>=0.

EXAMPLE

Northwest corner:

1 0 1 1 2 3

2 1 3 4 7 11

2 0 2 2 4 6

3 0 3 3 6 9

4 0 4 4 8 12

3 1 4 5 9 14

Row 6 of the Wythoff array is (14,23,37,60,...). Reverse recurrence gives

9=23-14, 5=14-9, 4=9-5, 1=5-4, 3=4-1, so that row 6 of A165357 is

(3,1,4,5,9,14,23,37,60,...).
