Presentation

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

A minimal faithful permutation representation — 3 generators on 32 points:

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