Presentation

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

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

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