Presentation

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

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

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

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

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