Presentation

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

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

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