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