Presentation

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

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

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