Presentation

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

A minimal faithful permutation representation — 4 generators on 32 points:

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