Presentation

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

A minimal faithful permutation representation — 5 generators on 32 points:

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