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