Presentation

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

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

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