Presentation

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

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

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