Presentation

minimal degree	μ(G) = 32
transitive degree	μ_t(G) = 128

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

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