FORMULA
Empirical for column k:
k=1: [linear recurrence of order 25] for n>33
k=2: a(n) = 6*a(n-3) -8*a(n-6) for n>13
k=3: a(n) = 6*a(n-3) -8*a(n-6) for n>11
k=4: a(n) = 4*a(n-3) for n>8
k=5: a(n) = 12*a(n-3) -32*a(n-6) for n>11
k=6: a(n) = 12*a(n-3) -32*a(n-6) for n>11
k=7: a(n) = 8*a(n-3) for n>8
