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