Presentation

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

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

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