Presentation

minimal degree	μ(G) = 32
transitive degree	μ_t(G) = 64

A minimal faithful permutation representation — 3 generators on 32 points:

(1,2,5,10,6,7,4,9)(3,11,12,15,13,16,14,8)(17,18,21,25,22,24,20,29)(19,23,28,31,27,32,26,30);(2,7)(4,5)(11,16)(12,14)(17,19)(18,23)(20,26)(21,28)(22,27)(24,32)(25,31)(29,30);(1,3)(2,8,7,15)(4,12)(5,14)(6,13)(9,11,10,16)(18,24)(19,26)(20,21)(23,30)(27,28)(31,32)
