Dan, Thanks for noticing that. I've amended it, together with the fact that the Taylor-Socolar tile isn't actually strongly aperiodic (there are tilings with translational symmetry), but rather distinctly more non-trivial than the Goucher lego or the SCD tile. Sincerely, Adam P. Goucher

Dear Adam,
In your very very nice CP^4 math blog, the August 23 entry includes this sentence:
----- The first strongly aperiodic monotile (which admits no infinite cyclic group of symmetries) was found by Jean Taylor and Joshua Socolar. -----
The link, however, leads to an arXiv paper with the author Taylor having the first name "Joan" rather than "Jean".
(I wondered about this, since I know the mathematician Jean Taylor, emerita at Rutgers.)
Regards from Berkeley,
Dan
