Presentation

minimal degree	μ(G) = 32
transitive degree	μ_t(G) = 256

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

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