Presentation

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

A minimal faithful permutation representation — 5 generators on 30 points:

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