Presentation

minimal degree	μ(G) = 32
transitive degree	μ_t(G) = 256

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

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