Presentation

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

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

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

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

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