Default What is this group?

on, I see that the automorphism group of a certain graph is described as 3^4:((2\times S_6).2).

I understand this group is a composition of Z_3^4,Z_2\times S_6,Z_2,but exactly what does the . and : represent? Is it semidirect product, wreath product, or something else? I've been unable to find more informations on this notation elsewhere..
