Presentation

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

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

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