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