Presentation

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

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

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