Presentation

minimal degreeμ(G) = 30
transitive degreeμt(G) = 672

A minimal faithful permutation representation — 4 generators on 30 points:

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