Presentation

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

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

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