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