Presentation

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

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

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