Presentation

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

A minimal faithful permutation representation — 2 generators on 32 points:

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