Presentation

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

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

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