Construct a 4 * 4 addition table of binary 2-bit strings modulo 2. For example, 01 + 11 = 10 and 11 + 11 = 00. Replace each element in the table by its decimal equivalent plus 1. For example, 11 is replaced by 4. Is the resulting table a Latin square? Generalize this method for constructing Latin squares of order n

I am providing the handwritten answer

To generalize let us see how 3-bit string addition modulo 2 and then addition of 1 to decimal value looks

Also we can see there is a swapping of all the 8 elemants in the middle from row 4 to row 5. So, we can write the swapping in following numbers for 3-bit string

2, 4, 2, 8, 2, 4, 2

Now, in order to generalize it for n we can say the swapping needs to take place in the following numbers from left

2, 4, 2, 8, 2, ......2^(n-1) ,2, 2^n, 2, 2^(n-1),.........,2, 8, 2, 4, 2

4. Consider bit strings with length l and weight k (so strings of l 0’s and 1’s, including k 1’s). We know how to count the number of these for a fixed l and k. Now, we will count the number of strings for which the sum of the length and the weight is fixed. For example, let’s count all the bit strings for which l + k = 11. (a) Find examples of these strings of different lengths. What...
