Presentation

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

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

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