Presentation

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

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

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