Presentation

minimal degreeμ(G) = 30
transitive degreeμt(G) = 128

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

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