-
regular and orientably-regular maps on closed surfaces having small Euler characteristic, listed by their type, up to duality
-
regular and orientably-regular maps on closed surfaces having small non-positive Euler characteristic, listed by their type, up to duality
-

These things were obtained in (over a period of time) with the help of the "LowIndexNormalSubgroups"
routine in MAGMA.
