How do you make a permalink to a specific article?

If there's more than one version, you can use the URL from the "All versions" link.,14
But if there's only one version, how to do you figure out what the cluser-ID is?

It turns out that the ID used int he "related articles" link:,14
is actually the cluster ID. I don't know what encoding is used. But fortunately it doesn't matter — you can actually use the encoded form of the cluster ID in the first URL:,14
