Presentation

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

A minimal faithful permutation representation — 4 generators on 32 points:

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