title: Irreducible set of a Functional Dependency
body: <p>I currently have the Set/Functional Dependencies:  </p>
  
  <p>Relation R{A, B, C, D, E, F } satisfies the following FDs:  </p>
  
  <pre><code>AB → C C→A BC → D ACD → B BE → C CE → FA CF → BD D →EF
  </code></pre>
  
  <p>I have the answer:</p>
  
  <pre><code>{A B → C, C → A, B C → D, B E → C, C E → F, C F → B D, D → E F}
  </code></pre>
  
  <p>However I know that irreducible sets cannot have two attributes on the right hand side.</p>
  
  <p>What am I doing wrong?</p>
