Presentation

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

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

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