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