Presentation

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

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

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

GAP

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

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