Presentation

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

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

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

GAP

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

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