... computations of the number of Latin squares of order 10. We also give counts of Latin rectangles with up to 10 columns, and estimates of the number of Latin squares of orders up to 15. Mathematics ... “random” normalized Latin square with rows R 1 , ,R n by this process: R 1 is the usual first row for a normalized square. For i =2, ,n, R i is chosen uniformly at 3 LATIN SQUARES OF OR...
