Presentation

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

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

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