Abstract
We consider the irreducible representations each of dimension 2 of the necklace braid group (). We then consider the tensor product of the representations of () and determine necessary and sufficient condition under which the constructed representations are irreducible. Finally, we determine conditions under which the irreducible representations of () of degree 2 are unitary relative to a hermitian positive definite matrix
