Presentation

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

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

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