GeoNit, I did a more detailed review of your matrices--and in addition to the typo KeenWink pointed out earlier, there are other bid possibilities missing:
One Acceptable/Five Free Rebids is missing:
ACDF
ADEF
ABCDF
One Acceptable/Six Free Rebids is missing:
ABFG
ACEF
ACEG
ACFG
ADEG
ABCEF
ABCEG
ABCFG
ABDEG
ABDFG
ACDEF
ACDFG
ABDEFG
Two Acceptable/One Free Rebid is missing:
AB
Three Acceptable/One Free Rebid is missing:
ACD
Three Acceptable/Two Free Rebids is missing:
AB
AC
BC
ABC
It's obvious that you have enough knowledge of the permutation determination to know where in the lists these should be inserted.
Thanks again for all your work on these!

p.s. As a doublecheck when creating matrices such as these, you can use Pascal's Triangle to determine how many occurances there should be of each quantity of terms. You can use it directly on "1 Acceptable/X Free Rebids", but you have to do a modified version when you have multiple acceptable zones.
When doing "1 Acceptable/X Free Rebids", the zero-th row of the Triangle (normally called "Row Zero", and consisting simply of "1") applies to "zero rebid zones"; the first row (consisting of "1 1") applies to "one rebid zone"; etc. For example, for six rebid zones, you need the sixth row of the Triangle, which is "1 6 15 20 15 6 1". This means that there will be one bid with one zone ("A"), six bids with two zones ("AB", "AC", etc.), fifteen bids with three zones ("ABC", "ABD", etc.), twenty bids with four zones ("ABCD", "ABCE", etc.), fifteen bids with five zones ("ABCDE", "ABCDF", etc.), six bids with six zones ("ABCDEF", "ABCDEG", etc.), and one bid with seven zones ("ABCDEFG"). If you've put together a "One Acceptable/X Free Rebids" matrix, and you don't have the appropriate number of terms per the Triangle, you've missed some. I won't get into the details about how to apply the Triangle to multiple acceptable bid zones--it needs to get multi-dimensional, which gets rather complicated, and is hard to describe via text--but it also works there.
