Table of n, a(n) for n=1..104.

FORMULA

M={M1, M1, M2} v[n]=M.v[n-1] a(n) = v[m][[n]] by Flattening the tensor

MATHEMATICA

(* v[1] is taken as a[n]=a[n-1]+a[n-2]+a[n-3] elements*) v[1] = {{0, 1, 1}, {1, 1, 2}, {1, 2, 4}} M1 = {{0, 1, 0}, {0, 0, 1}, {1, 0, 0}} M2 = {{1, 1, 1}, {0, 0, 1}, {0, 1, 0}} M = {M1, M1, M2} v[n_] := v[n] = M.v[n - 1] a = Table[v[n], {n, 1, 4}] aa = Flatten[a]
