Abstract (EN): In [1], we claim that we give a complete list of the possible degrees of a faithful transitive permutation representation of the groups of the toroidal regular maps. Indeed, the list given for type {4, 4} is complete; however, recently we were surprised with the existence of exceptional degrees for the map {3, 6}. After, we struggled to find the reason why there were some degrees missing in our classification. The fact is that there is a gap in one proof, having consequences in two of our main theorems. Our goal is to fill in that gap. In what follows, let G be the group of symmetries of a toroidal regular map of type {4, 4} or {3, 6}, and suppose G is represented as a faithful transitive permutation representation group of degree n. Let T be the translation group generated by unitary independent translations of order s defining the groups of {4, 4}s or {3, 6}s for s ¿ {(s, 0), (s, s)} (see [1]). We recall the following results.
