. "In combinatorial mathematics, a Latin rectangle is an r \u00D7 n matrix (where r \u2264 n), using n symbols, usually the numbers 1, 2, 3, ..., n or 0, 1, ..., n \u2212 1 as its entries, with no number occurring more than once in any row or column. An n \u00D7 n Latin rectangle is called a Latin square. An example of a 3 \u00D7 5 Latin rectangle is:"@en . . . . .
