Presentation

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

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

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