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