title: Non-repeating pseudo random number stream with 'clumping'
body: <p>I'm looking for a method to generate a pseudorandom stream with a somewhat odd property - I want clumps of nearby numbers.  </p>
  
  <p>The tricky part is, I can only keep a limited amount of state no matter how large the range is.  There are algorithms that give a sequence of results with minimal state (linear congruence?)  </p>
  
  <p>Clumping means that there's a higher probability that the next number will be close rather than far.  </p>
  
  <p>Example of a desirable sequence (mod 10): 1 3 9 8 2 7 5 6 4<br>
  I suspect this would be more obvious with a larger stream, but difficult to enter by hand.</p>
  
  <p>Update:<br>
  I don't understand why it's impossible, but yes, I am looking for, as Welbog summarized:</p>
  
  <ul>
  <li>Non-repeating </li>
  <li>Non-Tracking  </li>
  <li>"Clumped" </li>
  </ul>
