Presentation

minimal degree	μ(G) = 32
transitive degree	μ_t(G) = 64

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

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