Presentation

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

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

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