Presentation

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

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

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