✦ Synopsis
We prove that the self-complementary graphs having cyclic complementing permutation are Class 1 and that the regular self-complementary graphs are Class 2. We conjecture that a selfcomplementary graph is Class 2 if and only if it is regular.

The edges and faces of a plane graph are colored so that every two adjacent or incident of them are colored differently. The minimal number of colors for this kind of coloring is estimated. For the plane graphs of the maximal degree at least 10, the bound is the best possible. The proof is based on
## Abstract The class of self‐complementary symmetric graphs is characterized using the classification of finite simple group.
