Presentation

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

A minimal faithful permutation representation — 7 generators on 30 points:

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