Presentation

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

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

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