Presentation

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

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

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