Presentation

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

A minimal faithful permutation representation — 6 generators on 28 points:

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