Let \(\operatorname{Sing}_{n}\) denotes the semigroup of all singular self-maps of a finite set \(X_n=\lbrace 1, 2,\ldots, n\rbrace\). A map \(\alpha\in \operatorname{Sing}_{n}\) is called a \(3\)-path if there are \(i, j, k\in X_n\) such that \(i\alpha=j\), \(j\alpha=k\) and \(x\alpha = x\) for all...
