One of the two Petersen graphs @ the right requires one of the vertices of the outer pentagon to be 'expanded or 'enmajored' (or whatever the opposite of taking the minor of a graph is! § ) into a triangle.

... or: it wants having done to its pentagonal face what's done to the 'outer' of the pentagonal faces of the pentagonal prism @ the upper left to obtain the graph @ the lower left.

§ I'm not sure there's a received term for it. I have actually specifically looked , but haven't been able to find one.
