Presentation

minimal degreeμ(G) = 23
transitive degreeμt(G) = 112

A minimal faithful permutation representation — 4 generators on 23 points:

(2,6,5,3,4,7);(1,2,5,6,4,7,3)(13,19)(20,23);(8,10,11,16,12,17,18,22)(9,13,14,20,15,19,21,23);(8,9)(10,13)(11,14)(12,15)(16,20)(17,19)(18,21)(22,23)

GAP

Past the SmallGroups library coverage — no SmallGroups id. Construct it from a minimal faithful permutation representation:

gap> G := Group((2,6,5,3,4,7), (1,2,5,6,4,7,3)(13,19)(20,23), (8,10,11,16,12,17,18,22)(9,13,14,20,15,19,21,23), (8,9)(10,13)(11,14)(12,15)(16,20)(17,19)(18,21)(22,23));
