Presentation

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

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

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

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

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