Presentation

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

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

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