Presentation

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

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

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

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

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