Presentation

minimal degree	μ(G) = 31
transitive degree	μ_t(G) = 448

A minimal faithful permutation representation — 3 generators on 31 points:

(1,2,4,6,7,5,3)(16,18,19,25,20,26,28,30)(17,22,23,24,21,29,27,31);(8,10,11,15)(9,12,13,14)(17,21)(22,29)(23,27)(24,31);(2,3)(4,5)(6,7)(8,9,11,13)(10,14,15,12)(16,17,20,21)(18,24,26,31)(19,27,28,23)(22,30,29,25)
