Presentation

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

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

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

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

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