Presentation

minimal degreeμ(G) = 30
transitive degreeμt(G) = 128

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

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