Presentation

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

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

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