Presentation

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

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

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

GAP

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

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