Presentation

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

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

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

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