Presentation

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

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

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