COMMENTS
j is the offset when combining terms from the two initial sequences.
FORMULA
EXAMPLE
T(4,3) = Fibonacci(4)*Lucas(4+3) = 3*29 = 87.
Square array showing T(n,j) begins:
j=0 j=1 j=2 j=3 j=4 ..
n=1 1 3 4 7 11 ..
n=2 3 4 7 11 18 ..
n=3 8 14 22 36 58 ..
n=4 21 33 54 87 141 ..
... .. .. .. .. .. ..
PROG
(PARI) T(n, j) = fibonacci(2*n+j) - (-1)^n*fibonacci(j);
