| Abstract: | In this article the rooted planar near-4-regular Eulerian trails are enum erated and an explicit form ula for such m aps is presented. Further, the rooted near-4-regular Eulerian m aps on the torus are counted in an exact w ay. |
| Keywords: | Map enufunction Euler trail Lagrangian inversion near-4-regular Eulerian m ap(trail) |
