A n By 1 Diamond consists of two lines of n 
(2 or 3) and two single dancers, forming a 
diamond formation.  See diagrams below.

Note: The n By 1 Diamond concept is not well defined
and  seems to be limited to a specific set of calls.  Some callers want the
dancers in the Line of n to do their part as if the Line of
n was Solid.  Some callers want the dancers in the Line of
n to do their part working Concentric.
