Summary
| Description |
English: The two graph minors of Wagner's theorem, K5 (left) and K3,3 (right) in the nonplanar Petersen graph. The Petersen graph is shown with the small colored disks as vertices and with solid black edges. Its minors (shown in pale yellow) may be formed by deleting the red vertex and contracting the edges that lie within a single yellow circle. |
