Presentation

minimal degreeμ(G) = 30
transitive degreeμt(G) = 256

A minimal faithful permutation representation — 6 generators on 30 points:

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