Presentation

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

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

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