P.S. Funnily enough, Facebook Like Box code generator does accept lower numbers, and generates live example as well as code based on that.
e.g. generated by Facebook official code generator on the above link
<div class="fb-like-box" data-href="http://www.facebook.com/platform" data-width="200" data-show-faces="true" data-stream="false" data-header="true"></div>
