Presentation

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

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

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