Assign Agent Rules – maximum?

Is there a limit on the number of Assign Agent Rules that can be created?

I expect to support several organizations, departments and topical areas which require complex multiple conditions in order to assign the appropriate Ticket Agent.

My concern is there may be an arbitrary limit on the number of rules which may be created. If so, I may need to streamline my internal procedures for ticket assingment.

If there is no limit, then I would have no concerns in this area.
