摘      要:The original version of the article was published in [1]. Unfortunately, the original version of this article contains a mistake: in Theorem 6.2 appears that β(n, △) = (n-△ + 5)/4 but the correct statement is β(n, △) = (n -△ + 4)/4. In this erratum we correct the theorem and give the correct proof.
