Presentation

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

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

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