Presentation

minimal degreeμ(G) = 24
transitive degreeμt(G) = 128

A minimal faithful permutation representation — 5 generators on 24 points:

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

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

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