Presentation

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

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

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