Presentation

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

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

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