comment Graph Theory:Folkman Graph
A good start would be to give a definition/construction of Folkman's graph that will allow to describe its automorphism group. Unless you are happy with a proof involving Sage math :)

comment Graphs with 12 edges over the vertices $\{1,2,…,12\}$ have two vertices with a degree of 5
First of all, are you counting up to isomorphism of graphs or are the graphs labelled?

Hint. If you add an edge to a spanning tree you obtain a cycle. Adding distinct edges gives you distinct cycles.
