Presentation

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

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

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