Presentation

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

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

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