Presentation

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

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

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

GAP

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

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