Presentation

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

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

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