Presentation

minimal degree	μ(G) = 30
transitive degree	μ_t(G) = 1440

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

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