Presentation

minimal degree	μ(G) = 32
transitive degree	μ_t(G) = 512

A minimal faithful permutation representation — 3 generators on 32 points:

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