Presentation

minimal degree	μ(G) = 30
transitive degree	μ_t(G) = 672

A minimal faithful permutation representation — 3 generators on 30 points:

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