Single best value: this property generally contains a single value. If there are several, one would have preferred rank (Help)
Exceptions are possible as rare values may exist. Exceptions can be specified using exception to constraint (P2303). Known exceptions: imaginary number (Q9165172), Klein four-group (Q550593), system of equations (Q735660), nabla operator (Q334508), decreasing function (Q3075231), increasing function (Q3075182)
List of violations of this constraint: Database reports/Constraint violations/P2812#single best value, SPARQL
Distinct values: this property likely contains a value that is different from all other items. (Help)
Exceptions are possible as rare values may exist. Exceptions can be specified using exception to constraint (P2303). Known exceptions: butterfly curve (Q2465157), butterfly curve (Q2533777), bipolar coordinates (Q2383591), two-center bipolar coordinates (Q4087586)
