Presentation

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

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

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