Presentation

minimal degreeμ(G) = 24
transitive degreeμt(G) = 512

A minimal faithful permutation representation — 7 generators on 24 points:

(10,11)(17,18,20,22)(19,21,23,24);(5,6,8,7)(9,10,12,11)(19,23)(21,24);(14,16)(17,19)(18,21)(20,23)(22,24);(6,7)(13,14)(15,16)(17,19)(18,21)(20,23)(22,24);(3,4);(5,7,8,6)(9,11,12,10)(17,18)(19,24)(20,22)(21,23);(1,2)(3,4)

Conjugacy classes & character table

GAP

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

gap> G := Group((10,11)(17,18,20,22)(19,21,23,24), (5,6,8,7)(9,10,12,11)(19,23)(21,24), (14,16)(17,19)(18,21)(20,23)(22,24), (6,7)(13,14)(15,16)(17,19)(18,21)(20,23)(22,24), (3,4), (5,7,8,6)(9,11,12,10)(17,18)(19,24)(20,22)(21,23), (1,2)(3,4));
