Presentation

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

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

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