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