Presentation

minimal degreeμ(G) = 28
transitive degreeμt(G) = 256

A minimal faithful permutation representation — 7 generators on 28 points:

(13,14,17,18)(15,19,20,16)(21,22,25,23)(24,26,28,27);(5,6,7,8)(10,12)(14,18)(16,19)(21,23,25,22)(24,26,28,27);(9,10)(11,12)(13,15)(14,16)(17,20)(18,19);(3,4);(1,2)(3,4);(5,6)(7,8)(9,10)(11,12);(13,16)(14,15)(17,19)(18,20)(21,24)(22,26)(23,27)(25,28)

GAP

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

gap> G := Group((13,14,17,18)(15,19,20,16)(21,22,25,23)(24,26,28,27), (5,6,7,8)(10,12)(14,18)(16,19)(21,23,25,22)(24,26,28,27), (9,10)(11,12)(13,15)(14,16)(17,20)(18,19), (3,4), (1,2)(3,4), (5,6)(7,8)(9,10)(11,12), (13,16)(14,15)(17,19)(18,20)(21,24)(22,26)(23,27)(25,28));
