Presentation

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

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

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