COMMENTS
The table is created from a nucleus (0,0,1,-1) in the upper row, periodic in each row with length 4 and extended downwards to further rows with the Pascal/Galton mixing coefficients (0,-2,1).
Each row may be regarded as coefficients in recurrences of a group of sequences, b_i(n) = Sum_{k=1..4} T(i,k)*b_i(n-k).
FORMULA
EXAMPLE
The table starts:
0, 0, 1, -1, 0, 0, 1, -1,...
0, 1, -3, 2, 0, 1, -3, 2,...
1, -5, 8, -4, 1, -5, 8, -4,...
-7, 18, -20, 9, -7, 18, -20, 9,...
and only the first 4 columns (the non-redundant information) build the sequence.
