Presentation

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

A minimal faithful permutation representation — 3 generators on 32 points:

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