Presentation

minimal degree	μ(G) = 32
transitive degree	μ_t(G) = 128

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

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