Let \(M=(m_{ij};\;i,j\in I)\) be a Coxeter matrix. The Artin group \(G(M)\) of large type \((m_{ij}\geq~3; i\neq j)\) is torsion-free, the set \(\{a^ 2_ i,\;i\in I\}\) freely generates a free subgroup of \(G(M)\), the conjugacy problem in \(G(M)\) (as in the Coxeter groups of large type) is solvable.
