Presentation

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

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

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