Presentation

minimal degreeμ(G) = 28
transitive degreeμt(G) = 512

A minimal faithful permutation representation — 6 generators on 28 points:

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