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