Presentation

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

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

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