Presentation

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

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

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

GAP

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

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