FORMULA
Empirical for column k:
k=1: a(n) = 2*a(n-1) +4*a(n-2) -3*a(n-3)
k=2: [order 10]
k=3: a(n) = 8*a(n-1) +26*a(n-2) -166*a(n-3) +96*a(n-4) +198*a(n-5) -81*a(n-6)
Empirical for row n:
n=1: a(n) = 2*a(n-1) +2*a(n-2)
n=2: a(n) = 2*a(n-1) +2*a(n-2)
n=3: a(n) = 6*a(n-1) +12*a(n-2) -8*a(n-3)
n=4: [order 10]
n=5: [order 37]
n=6: [order 85]
