Presentation

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

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

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