 Graph G1 {
   Vertices: 1, 2, 3, 4
   Edges: (1,2) (1,3) (2,4) (3,4) (2,3)
 }

 Graph G2 {
   Vertices: 1, 2, 3, 4
   Edges: (1,2) (1,4) (2,4) (3,4) (2,3)
 }

 G1 isomorphs to G2 by swapping 3 and 4

 G3 is an automorphism for G1:

 Graph G3 {
   Vertices: 1, 2, 3, 4
   Edges: (1,2) (1,3) (1,4) (3,4) (2,3)
 }

Graph G1 { Vertices: 1, 2, 3, 4 Edges: (1,2) (1,3) (2,4) (3,4) (2,3) } Graph G2 { Vertices: 1, 2, 3, 4 Edges: (1,2) (1,4) (2,4) (3,4) (2,3) } G1 isomorphs to G2 by swapping 3 and 4 G3 is an automorphism for G1: Graph G3 { Vertices: 1, 2, 3, 4 Edges: (1,2) (1,3) (1,4) (3,4) (2,3) }
