Presentation

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

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

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