Very clever anagram; they're not easy to do. It's good to see another person trying to accomplish Carroll's encouragement to rearrange the letters of what one has written. The real question is whether Carroll actually did what he encouraged others to do. I think Yes; I'm guessing you think No.
Re the lack of an Index, I agree with you that it's a crime. It's clear you read the e-book version of the work. Perhaps there are e-book publishers now who retain the original page numbers; but I didn't find one at the time. The original hard copies of the works are indexed. I don't have the e-books here, but I believe the Notes were included in both e-books.
