Metaproperties:
This property has the following metaproperties
- Morita invariant
- passes to $eRe$ for any full idempotent $e$
- passes to matrix rings
- passes to the center
- stable under finite products
- passes to quotient rings
This property
does not have the following metaproperties
- passes to subrings
(Counterexample: $R_{ 6 }$ is a subring of $R_{ 101 }$)
- stable under products
(Counterexample: $R_{ 57 }$)
- forms an equational class
(counterexample needed)
- passes to polynomial rings
(Counterexample: $R_{ 7 }$ is the polynomial ring of $R_{ 2 }$)
