Presentation

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

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

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

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

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