Presentation

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

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

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