Pascal-like triangle with index of asymmetry (y=2) and index of
obliqueness (z=0) read by rows with recurrence G(n, k): G(n, 0)=G(n+1,
n+1)=1, G(n+2, n+1)=2, G(n+3, n+1)=4, G(n+4, k)=G(n+1, k-1)+G(n+1,
k)+G(n+2, k)+G(n+3, k) for k:=1..(n+1).

EXAMPLE
|
Pascal-like triangle (y=2, z=0) begins:
If 1
1 1
1 2 1, then a(1)=2.
If 1 4 2 1
1 8 4 2 1
1 15 9 4 2 1
1 28 19 9 4 2 1, then a(2)=19.
If 1 52 40 19 9 4 2 1
1 96 83 41 19 9 4 2 1, then a(3)=41 and a(4)=83.
