Presentation

minimal degreeμ(G) = 30
transitive degreeμt(G) = 192

A minimal faithful permutation representation — 3 generators on 30 points:

(1,2)(7,12)(8,15,27,16,29,14)(9,10,11,19,17,20)(13,30,22,25,26,23)(18,28)(21,24);(3,4,5,6)(8,13)(9,17)(10,19)(11,20)(14,23)(15,24)(16,25)(18,30)(21,29)(22,27)(26,28);(7,8,13)(9,18,22)(10,14,26)(11,15,21)(12,16,25)(17,27,30)(19,28,23)(20,29,24)
