Presentation

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

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

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

GAP

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

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