Presentation

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

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

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