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