Does Facebook have a list of icons that others can use?

Question

For Facebook's 16x16 pixel icon, the following url is used fairly a lot, but this isn't stated by Facebook that people can use this, is it?

http://static.ak.fbcdn.net/images/icons/favicon.gif

Is there any official list of icons from Facebook that people can use their own site for Facebook Connect?

Answer 1

See the Facebook promotional guidelines and the official "sharing" widgets.
