Multiple

Multiple:

A multiple system is the state of being more than one entity in one physical body where the identites of headmates are more distinct.

This can often be used to include other attributes, like lack of memory sharing, lack of internal communication, or lack of co-consciousness and resulting time loss, but partitionary is in fact a better descriptor for such experiences, as multiple describes identity and not memory.

The term is sometimes used as opposed to median, where distinction between system members is less distinct than with a multiple system.
