Presentation

minimal degree	μ(G) = 32
transitive degree	μ_t(G) = 128

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

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