Presentation

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

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

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

GAP

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

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