Presentation

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

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

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