Presentation

minimal degreeμ(G) = 42
transitive degreeμt(G) = 512

A minimal faithful permutation representation — 4 generators on 42 points:

(4,8,9,10)(11,12,16,23,20,31,38,28,18,25,37,22,34,21,39,41,19,26,36,42,33,30,32,40,17,24,15,35,14,13,27,29);(4,9)(8,10);(3,4,5,8,7,9,6,10)(11,13,18,30,19,21,17,31)(12,20,24,34,26,33,25,14)(15,23,16,35,37,42,36,22)(27,29,38,40,39,41,32,28);(1,2)(3,5,7,6)(4,8,9,10)(11,14,17,33,19,34,18,20)(12,21,24,31,26,13,25,30)(15,32,36,39,37,38,16,27)(22,40,23,41,35,28,42,29)
