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