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