<p>The <a href="http://en.wikipedia.org/wiki/Conway_base_13_function" rel="nofollow">Conway base 13 function</a> has to be the weirdest function I know. This function is continuous nowhere, yet it satisfies the intermediate value theorem. Only John Conway...</p>

<p>What do you mean? The action isn't transitive, that's all. Note also that an isometry is not necessarily bijective, so you can only say the group of <i>bijective</i> isometries embeds in $S_n$.</p>

Oops, thanks to both, didn't catch that.

Perhaps you're wondering whether we can narrow down the possible isomorphism type of $Iso(X,d)$. I would start by characterizing the isomorphism types of isometry groups of finite metric spaces in general.
