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

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