Presentation

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

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

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