Presentation

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

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

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