Presentation

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

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

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