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