Presentation

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

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

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