> | ## 4.24 User defined types User defined types are (non-empty) lists with a fixed size whose element can be accessed by names (and not indices). These elements have a predefined type (which can also be a user defined type). If these elements depend on a ring they can only be accessed if their base ring is the current base ring. In contrast to usual lists the elements of a user defined type may belong to different rings.
