UpperBoundMinimumDistance( C )
In this form, UpperBoundMinimumDistance returns an upper bound for the
minimum distance of code C. For unrestricted codes, it just returns the
word length. For linear codes, it takes the minimum of the possibly known
value from the method of construction, the weight of the generators, and
the value from the table (see BoundsMinimumDistance).

UpperBoundMinimumDistance( n, k, F )
In this form, UpperBoundMinimumDistance returns an upper bound for the
minimum distance of the best known linear code of length n, dimension
k over field F. It uses the mechanism explained in section
BoundsMinimumDistance.
