Presentation

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

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

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