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