title: Removing lines with consecutive pairs
body: <p>I have a text file with a lot of number combinations. It looks like this:</p>
  
  <pre><code>1 2 3 4 5 6
  1 2 3 4 5 7
  1 2 3 4 5 8
  1 2 3 4 5 9
  1 2 3 4 5 10
  </code></pre>
  
  <p>Every line has 6 numbers with a space between each number. Numbers go from 1 to 37.</p>
  
  <p>I need an AWK command to remove any line with 2 or 3 consecutive pairs.</p>
  
  <p>For example:</p>
  
  <p><b>1 2</b> 6 9 <b>13 14</b></p>
  
  <p><b>4 5 18 19 25 26</b></p>
  
  <p>Thanks!</p>
