Presentation

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

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

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