I just found my new personalized license plate! (Or phone number, removing the 9)
I’ve always memorized that last word as “obscurity”, which has 9 letters. “Circles” has always remained such, and never noticed it (and doesn’t sound right as a singular object)
I’ve read Cadaeic Cadenza, which is a story written with word lengths representing the first 3835 digits of pi, so, I suppose if you memorize it … (I have yet to read Not A Wake by the same author, apparently the longest work written to represent the decimals of pi, using the first 10.000.)
