Обложка журнала Scientific American за ноябрь 1959 года воспроизводит интересное художественное полотно. Его создала художник журнала Эми Казаи. На картине изображен греко-латинский квадрат 10-го порядка (см. рис. 4). Десять цифр квадрата были заменены десятью различными красками, так что каждая ячейка окрашена соответствующей парой красок.
Краски наружной области каждой ячейки образуют один латинский квадрат, краски внутренней области — другой. Каждый цвет появляется только один раз внутри ячейки и один раз снаружи. Оригинал картины госпожи Казаи был куплен Ремингтоном Рэндом и подарен Паркеру.

Displaying a 7 × 7 Latin square, this stained glass window honors Ronald Fisher, whose Design of Experiments discussed Latin squares. Fisher's student, A. W. F. Edwards, designed this window for Caius College, Cambridge.

This picture was painted by a friend according to my idea.
The painting depicts the concentric magic cube of order 7 constructed from prime numbers.



The picture is published in my work "Concentric Magic Cubes of prime numbers", included in the collection
https://www.amazon.com/Topics-Recreational-Mathematics-Charles-Ashbacher/dp/1514317516/ref=sr_1_6?ie=UTF8&qid=1434136023&sr=8-6&keywords=Charles+Ashbacher

This is a fragment of the picture
