Presentation

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

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

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