Presentation

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

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

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