Presentation

minimal degree	μ(G) = 32
transitive degree	μ_t(G) = 512

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

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