Presentation

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

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

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