+# Equivalent Class Axiom with no Genus
+
+**Problem:** An equivalent class axiom of the kind C = R some A is nearly always an indication of a problem. It basically means that anything that is R related to an A is equal to the class. While this is sometimes legit, most often this is accidental.
+
+**Solution:** Add a genus to the class expression like: C = B and R some A.
