Presentation

minimal degreeμ(G) = 32
transitive degreeμt(G) = 256

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

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