I've now added REDUCED into the algebra (sec 12) peoperly now.  It didn't make 
the LC doc due to time.

The key definition that defines the cardinality is:

"""card[Reduced(X)](y) is between 1 and card[X](y)"""

X is a sequnce, y a solution in the sequence.  See rq25.

and there is a note after the defintion:

"""
The Reduced solution sequence modifier does not guarantee a defined cardinality.
"""
