Presentation

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

A minimal faithful permutation representation — 3 generators on 32 points:

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