Presentation

minimal degree	μ(G) = 32
transitive degree	μ_t(G) = 128

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

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