Presentation

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

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

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