AbstractA set of generating relations of the full transformation semigroup Σn consisting of all mappings of the set Ω = {1, …, n} into itself with respect to a natural system of generators {γji, σji} (defined in Section 1) is given. The set of relations (1)∼(15) given in Section 1 turns out to be a set of generating relations
