Line 37: * Each column containing a leading {{math\|1}} has zeros in all its other entries. ~~The~~If the first two conditions are verified, the last condition is equivalent to: * Each column containing a leading {{math\|1}} has zeros in all entries above the leading {{math\|1}}. While a matrix may have several echelon forms, its reduced echelon form is unique. Given a matrix in reduced row echelon form, if one permutes the columns in order to have the leading {{math\|1}} of the {{mvar\|i}}th row in the {{mvar\|i}}th column, one gets a matrix of the form
