000170299 5203_ $$aAmazing matrices arise in several important combinatorial problems. In [13], a question was raised concerning how to obtain an LU factorization of these matrices. In this work, we answer this question for the case and introduce a high relative accurate algorithm to compute such a factorization. Numerical experiments are provided to demonstrate the accuracy and effectiveness of the proposed method.
