Presentation

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

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

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