Presentation

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

A minimal faithful permutation representation — 5 generators on 28 points:

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