Presentation

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

A minimal faithful permutation representation — 6 generators on 42 points:

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