Presentation

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

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

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