Presentation

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

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

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