Presentation

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

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

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