Presentation

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

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

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