Presentation

minimal degreeμ(G) = 30
transitive degreeμt(G) = 512

A minimal faithful permutation representation — 5 generators on 30 points:

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