Presentation

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

A minimal faithful permutation representation — 5 generators on 23 points:

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

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

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