Presentation

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

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

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

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

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