Presentation

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

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

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