Presentation

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

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

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