Presentation

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

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

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