Presentation

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

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

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