Was it 116 pages?
Interestingly, 116 pages were the number of pages — dictated by Oliver Cowdery — needed to get up to Mosiah 3. The lost manuscript contained the Book of Mormon narrative from Lehi through Mosiah 2.
Martin Harris’ brother, Emer (distant ancestor of Dallin Harris Oaks), reported that the lost manuscript consisted of over 200 pages.
Contrary to what people may know (and not discovered till the 1990s), Joseph resumed translating from Mosiah to the end of Moroni. Only then did they use the small plates of Nephi to complete their task and add the (now) first books in this scripture.
