bicartesian category

A category is bicartesian if it is both cartesian and cocartesian, that is if both it and its opposite may be made into cartesian monoidal categories.

A bicartesian category which is also cartesian closed is a bicartesian closed category. Bicartesian closed categories are usually not cocartesian closed.
