Presentation

minimal degreeμ(G) = 28
transitive degreeμt(G) = 128

A minimal faithful permutation representation — 3 generators on 28 points:

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