Presentation

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

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

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

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

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