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