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