The Webinar on Playful Squares took place on Wednesday, June 9th, 2021 from 12 pm until 1 pm, with Guido Ramellini, advisor to the Museum of Mathematics of Cataluña (MMACA), as our invited speaker. This virtual event was free and open to the general public.
The invited speaker started the virtual event by presenting on Latin squares and Greco-Latin squares. Guido Ramellini then described the magic squares and the tragic squares, which are those in which the same value of the sums of the rows, columns and diagonals is not repeated. The speaker also explained the Game of Skyscrapers and invited all the participants to play. This virtual event was co-organized with the Museum of Mathematics of Cataluña (MMACA).
