Presentation

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

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

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