"WebAs a Möbius ladder, the Wagner graph is nonplanar but has crossing number one, making it an apex graph. It can be embedded without crossings on a torus or projective plane, so it is also a toroidal graph. It has girth 4, diameter 2, radius 2, chromatic number 3, chromatic index 3 and is both 3-vertex-connected and 3-edge-connected. " - Diameter in a graph

Its diameter is $n$, since the distance between two vertices maximally far apart is only $n$: there is a path of length $n+1$ between them, but it’s the longer way round the cycle. The girth, however, is clearly $2n+1$.
