Presentation

minimal degree	μ(G) = 32
transitive degree	μ_t(G) = 256

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

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