• All <strong>variables</strong> <strong>and</strong> <strong>values</strong> are interchangeable<br />
• i.e. a=b=1<br />
• Ordering signatures = “decreasing<br />
sequence”<br />
• X1 ≤ X2 ≤ .. ≤ Xn<br />
• |{ i | Xi=k}| ≥ |{ i | Xi=k+1}| for all k<br />
• Consider 1,1,1,2,2,3,4 <strong>and</strong> 1,1,1,2,2,3,5<br />
or 1,1,2,2,2,3,4
