A\nmagic rectangle arranges the integers 1 to p*q so that all row\nsums are equal and all column sums are equal; it exists exactly\nwhen p and q have the same parity, excluding 2 x 2 and\ndegenerate single-row/column cases (Hagedorn, 1999,\n). When p and q have\nopposite parity a nearly magic rectangle exists instead, with\nconstant sums along one direction and sums differing by at most\none along the other (Chai, Singh and Stufken, 2019, Journal of\nCombinatorial Designs 27(6), 368-376). Implements the\nconstructions of De Los Reyes, Das, Midha and Vellaisamy (2009)\nfor even by even orders, Chai, Das and Midha (2013) for odd by\nodd orders, and Chai, Singh and Stufken (2019) for the nearly\nmagic (even by odd) case.", "License": "MIT + file LICENSE", "URL": "https://github.com/Arijitray2/magic-rectangles,\nhttps://arijitray2.github.io/magic-rectangles/", "BugReports":
