Presentation

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

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

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