comment Is there any algorithm to find Isomorphism function between two graphs?
"The evidence however suggests that it is NP-intermediate." --- There are people who feel that the existence of the quasi-polynomial algorithm suggests that GI is in P, actually.

@Vortico: It's not the size of the faces which matters for the historical definition. It's the fact that after the rotation, still every vertex is surrounded by a triangle and 3 squares.

comment Finding the recurrence relation.
@YvesHalimi There is a standard method using linear algebra. Write $\begin{pmatrix}g(n)\\X(n)\end{pmatrix} = A\begin{pmatrix}g(n-1)\\X(n-1)\end{pmatrix}$ with a suitable matrix $A$ and compute $A^n$. Anyway, this discussion was about finding a recurrence relation, so you should open a new question for it.
