Presentation

minimal degree	μ(G) = 31
transitive degree	μ_t(G) = 224

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

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