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