Presentation

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

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

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