Presentation

minimal degree	μ(G) = 32
transitive degree	μ_t(G) = 512

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

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