Presentation

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

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

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