Presentation

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

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

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