FORMULA
Empirical for column k:
k=1: a(n) = 4*a(n-1) -3*a(n-2)
k=2: a(n) = 7*a(n-1) +2*a(n-3) -8*a(n-4) for n>5
k=3: [order 8]
k=4: [order 31]
k=5: [order 94]
Empirical for row n:
n=1: a(n) = 2*a(n-1) for n>2
n=2: a(n) = 5*a(n-1) -2*a(n-2) -4*a(n-3) for n>5
n=3: a(n) = 9*a(n-1) +16*a(n-2) -50*a(n-3) -72*a(n-4) -32*a(n-5) -32*a(n-6) for n>8
n=4: [order 21] for n>23
n=5: [order 65] for n>67
