Presentation

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

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

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