Squares leading to an autosequence of the first kind.
The third sequence of the array
A060576(n+1)= 0, 1, 1, 1, 1, 1, 1, 1, 1, 1, ...
A289207(n)= 0, 0, 0, 1, 2, 3, 4, 5, 6, 7, ...
a(n)= 0, -1, -1, 0, 1, 4, 9, 16, 25, 36, ...
0, 10, 10, 5, 0, 1, 8, 27, 64, 125, ...
0, -113, -113, -68, -23, 0, 1, 16, 81, 256, ... .
The first full vertical is (-1)^n*A033312(n).
From 0, the first two nonzero antidiagonals are 0, -1, 10, -113, 1526, ... = (-1)^n* A176824(n+1).
