Presentation

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

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

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