Presentation

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

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

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