What are the rules to write Pauli's spin matrices in higher-order matrices (especially in 4x4 matrices)

It's not clear what you are after? Do you mean the case ##s=3/2##? Then it's not the Pauli matrices anymore of course, because they represent ##s=1/2## and thus live in another spinor space.

I think the TS refers to constructing representations of the Clifford algebra via direct products of Pauli matrices, but I'm not sure. Could you give a (textbook) reference or some background, Pallab?

the question that can we express Pauli's 2x2 matrices for spin 1/2 in higher-order matrices, say 3x3, 4x4 arose in my mind.
