Presentation

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

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

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