Presentation

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

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

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