Vivid proofs of generalisations can be located in a particular, well-chosen example.</p> <p>This month we have worked with Tim Rowland to create problems where such generic examples can be found, and we invite you to explore and notice what is generalisable.</p> <p> </p> <h3>This month</h3></mdoxml> 2 3 0 0 0 0 0 Header for March 2012 front page
