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)(15,17,19,25)(16,21,20,23)(18,27,26,24)(22,29,28,30);(11,12,13,14)(16,20)(17,24)(18,26)(21,29)(23,30)(25,27);(9,10)(12,14)(15,16)(17,23)(18,22)(19,20)(21,25)(24,29)(26,28)(27,30)
