Presentation

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

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

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