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