Presentation

minimal degree	μ(G) = 32
transitive degree	μ_t(G) = 1024

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

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