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