Presentation

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

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

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