  is close to what I need - however I require a solution where it keeps the combinations in order and excludes repetition based on this order.
  i.e.
  a data set of 1 2 3 4  would show the product of:</p>
  
  <blockquote>
    <p>1 1+2 1+3 1+4 1+2+3 1+2+4 1+3+4 1+2+3+4 </p>
    
    <p>2 2+3 2+4 2+3+4</p>
    
    <p>3 3+4</p>
    
    <p>4</p>
  </blockquote>
  
  <p>i.e</p>
  
  <blockquote>
    <p>1 3 4 5 6 10</p>
    
    <p>2 5 6</p>
    
    <p>3 7</p>
    
    <p>4</p>
  </blockquote>
  
  <p>Is this possible in Google Sheets / Excel without a script?</p>
  
  <p>Thanks</p>
