Presentation

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

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

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