Presentation

minimal degreeμ(G) = 24
transitive degreeμt(G) = 256

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

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

GAP

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

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