I had a dyslexic coworker, and it drove me crazy when he took phone messages for me and wrote down phone numbers. I usually found that his transposition was in the middle of the final, four-digit group. If he took down 634-4367 as the number and it didn't work, I often found that 634-4637 would be the correct number. But I tried 4637 and a number of other permutations here, and nothing tied to the "Battle Hymn of the Republic."
'Tis a puzzlement.
