Presentation

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

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

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