Presentation

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

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

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