Hi Martin, A469, column 2, line -11: the name should be Leontief, Wassily Wassilyevich Thanks, but that was reported in the 2020 tune-up and Knuth declined to change it. I quote his (handwritten) reply: dek> It's Wassilyevich in Russian but Wassily in English --- he sent dek> me a postcard saying that, on 25 Feb 1983. Best, Karl
