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

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