FORMULA
Empirical for column k:
k=1: a(n) = 6*a(n-1) -8*a(n-2)
k=2: a(n) = 8*a(n-1) -7*a(n-2)
k=3: a(n) = 16*a(n-1) -21*a(n-2) +6*a(n-3)
k=4: a(n) = 31*a(n-1) -35*a(n-2) +5*a(n-3)
k=5: [order 11]
k=6: [order 22]
Empirical for row n:
n=1: a(n) = 4*a(n-1) -3*a(n-2)
n=2: a(n) = 6*a(n-1) +a(n-2) -6*a(n-3) for n>4
n=3: a(n) = 13*a(n-1) -5*a(n-2) -47*a(n-3) +52*a(n-4) -12*a(n-5) for n>6
n=4: [order 11] for n>12
n=5: [order 27] for n>28
n=6: [order 87] for n>88
