A140044 = the analogous sequence for Z/5Z; A095897 for Z/4Z and A007070 for Z/3Z.

Let X = the Z/6Z addition table considered as a matrix: [0,1,2,3,4,5; 1,2,3,4,5,0; 2,3,4,5,0,1; 3,4,5,0,1,2; 4,5,0,1,2,3; 5,0,1,2,3,4]. a(n) = term (1,2) of X^n.

a(3) = 495 since term (1,2) of X^3 = 495

Cf. A140044, A095897, A007070.
