Presentation

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

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

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