Presentation

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

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

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