Presentation

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

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

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