A sequence will never generate duplicate values
The MAXVALUE of a sequence can be equal to the MINVALUE
It is not possible to create a sequence that generates a constant since the INCREMENT value must be greater than zero
When a sequence cycles back to either the MAXVALUE or MINVALUE, it will always be equal to the specified value of either of these two boundaries
