Presentation

minimal degreeμ(G) = 28
transitive degreeμt(G) = 512

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

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