I'm not sure. A real expert from the list will probably tell you what the
cause of the overflow is.
As for finding the mean hamming distance, have you considered something like
the following:
hammingDistance xs ys = length (filter not (zipWith (==) xs ys))
meanHammingDistance xss yss = sumHDs / cntHDs
where
hds = map (uncurry hammingDistance) [(xs, ys) | xs <- xss, ys <- yss]
sumHDs = fromIntegral (sum hds)
cntHDs = fromIntegral (length hds)
