Presentation

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

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

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