Presentation

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

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

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