Presentation

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

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

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

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

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