Presentation

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

A minimal faithful permutation representation — 5 generators on 32 points:

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