Presentation

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

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

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