Construction similar to the Kronecker Product There is a method reminiscent of the Kronecker product of two matrices, that builds an nm × nm magic square from an n × n magic square and an m × m magic square.
Others have very different names (outer product, tensor product, Kronecker product) but convey essentially the same idea.
Then, the matrix describing the tensor product S ⊗ T is the Kronecker product of the two matrices.
The outer product is simply the Kronecker product, limited to vectors (instead of matrices).
The tensor product, outer product and Kronecker product all convey the same general idea.
