jeff4021 on "Simple permalink question for a noob"

I am going to make this as simple as possible. My site is http://www.zendental.net, used for content not a blog. We are using permalinks.

If you navigate to http://www.zendental.net/contact-zendental-dental-lab you will see our contact page. Under our list of pages in wp-admin, we have a page titled "Contact Zendental" and it has the above permalink "contact-zendental-dental-lab" indicated.

However, if you navigate to http://www.zendental.net/contact, it will "redirect" to the same page listed above.

We have no redirect plugins installed except for the "Easy HTTPS (SSL) Redirection" plugin, which has no features for what I am talking about. We have no other pages with "contact" as a permalink.

So my question is simple, where is the "redirect" from /contact to /contact-zendental-dental-lab coming from?

Also, along the same lines, if you navigate to http://www.zendental.net/gobbledeegook696969 it redirects to our home page http://www.zendental.net (however in the title it indicates "page not found").

Please help me figure out where all these, redirects, as I would refer to them, are coming from.

Thank you!!
