COMMENTS
Potočnik et al. refer to these as arc-transitive connected cubic vertex-transitive graphs.
Marston Conder (Email to N. J. A. Sloane, May 08 2017) remarks that "the first 5000 terms of A091430 are the same as the first 5000 terms of this sequence, with the exception of the 5th and 14th terms (corresponding to the Petersen graph and the Coxeter graph). I verified this soon after completing the determination of all connected symmetric 3-valent graphs of order up to 10000, in June 2011."

EXAMPLE
The first example is K_4 with 4 nodes, thus a(2) = 1.
