Correction: April 30, 2020

In my blog entry about the postponement of the 2020 Olympics to 2021, "Let the Games Begin Later", I referred to them as the Games of the XXII Olympiad, which was in fact the official name of the 1980 Moscow Olympics, the mistake owing to a missing Roman digit; the 2020 - now 2021 - Olympics will be the Games of the XXXII Olympiad.  Even if they're canceled entirely, because  either way, the 2024 Olympics will be still be the Games of the XXXIII Olympiad.  I regret the earlier typo.  (I had to fix a couple of other typos in that post as well.)
