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