Presentation

minimal degree	μ(G) = 32
transitive degree	μ_t(G) = 256

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

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