One of the interesting points in the above list is the lack of numbering. You may have noted that 112 is not in the above list for example. But if you go to any Site Setting page within a MOSS site and in the Site Actions option click People & Group which takes you to a page that displays users and groups. Right hand click this page and view HTML source on this page. Schroll down to the bottom of the page and what you will notice is a hidden object in the HTML referencing the ListTemplate ID that displays the value of 112. INTERESTING!
