Presentation

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

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

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