Presentation

minimal degree	μ(G) = 32
transitive degree	μ_t(G) = 256

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

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