Presentation

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

A minimal faithful permutation representation — 4 generators on 32 points:

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