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