Final answer:
Typically, each hex can have one owner at a time, except for the special hex mentioned in the question, which may have unique rules. This is common in board games where hexes represent territories. The special hex could be an exception with multiple owners or a unique status.
Step-by-step explanation:
The number of owners each hex can have in a game or a mathematical context will depend entirely on the rules specified within that system. Excluding one special hex mentioned in the question, it's typical for each hex to be assigned only one owner at a time. This is especially true in board games or territorial control games where players vie for dominance over different hexagonal regions represented on the board. The special hex mentioned might be an exception due to its characteristics or importance in the game, which could allow it to have multiple owners or a unique status.
Now, if we are to look at this from a property ownership perspective outside the context of gaming, the idea of multiple ownerships can exist, such as joint tenancy or tenants in common. However, this is unlikely the context the question is referring to, as 'hex' is not a term typically used in real estate or property law.
Without additional context, it is challenging to provide a more specific answer. Nonetheless, in most cases where hex ownership would apply (like a board game), there is usually a single entity or player assigned to each hex at any given time.
