FilledSmallSquareDecompose[poly, x] decomposes a polynomial, if possible, into a composition of simpler polynomials.

FilledSmallSquareDecompose gives a list of the polynomials which can be composed as to give the original polynomial.

FilledSmallSquare The set of polynomials is not necessarily unique.

FilledSmallSquare Decomposition is an operation which is independent of polynomial factorization.
