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