Presentation

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

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

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