There are a number of other distances which can be used, for
example the 'Lee distance'. When F={0,1,...,n-1} the Lee distance
between a,b in F is defined as min(|a-b|,n-|a-b|). For two vectors x
and y defined over Fn, the Lee distance is calculated by
summing the lee distance of the pairs xi, yi.
Most commonly F={0,1,2,3} as this case proves useful in a number of
areas.
