Presentation

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

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

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