Presentation

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

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

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