Presentation

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

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

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