Presentation

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

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

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

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

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