Presentation

minimal degree	μ(G) = 32
transitive degree	μ_t(G) = 64

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

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