Presentation

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

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

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