Presentation

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

A minimal faithful permutation representation — 3 generators on 32 points:

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