Presentation

minimal degreeμ(G) = 28
transitive degreeμt(G) = 480

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

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