The first part of the list had 20 names. At the end of the first group is a total number of hides of land given as 66, 100. The numbers of hides for each group add up to 66,100 so the number is correct. The second group of 15 names has a total under it listed at 242,700 hides. But this is incorrect. If you add up the hides for each of the names in this group it totals 244,100. These are almost certainly math errors.
