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