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