Presentation

minimal degreeμ(G) = 32
transitive degreeμt(G) = 128

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

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