title: What's a regex that matches all numbers except 1, 2 and 25?
body: <p>There's an input of strings that are composed of only digits, i.e., integer numbers. How can I write a regular expression that will accept all the numbers except numbers 1, 2 and 25?</p>
  <p>I want to use this inside the <a href="http://www.beanio.org/2.0/docs/reference/index.html#RecordIdentification" rel="nofollow noreferrer">record identification</a> of BeanIO (which supports regular expressions) to skip some records that have specific values.</p>
  <p>I reach this point <code>^(1|2|25)$</code>, but I wanted the opposite of what this matches.</p>
