Four variants of \textit{H. Y. Huang}'s method [J. Optimization Theory Appl. 16, 429-445 (1975; Zbl 0291.90038)] for the numerical solution of systems of linear equations are derived. The error propagation for the zero eigenvalues of the orthogonal projection matrices is also considered. Numerical examples are not given.
