Presentation

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

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

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