Presentation

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

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

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