Construct a completion of the 3 -by- 6 Latin rectangle \(\left[\begin{array}{llllll}0 & 1 & 2 & 3 & 4 & 5 \\ 4 & 3 & 1 & 5 & 2 & 0 \\\ 5 & 4 & 3 & 0 & 1 & 2\end{array}\right]\)
Compute the addition table and the multiplication table for the integers mod 4 .
Prove that, if we interchange the rows of a Latin square in any way and inter. change the columns in any way, the result is always a Latin square.
Construct a completion of the semi-Latin square $$\left[\begin{array}{lllllll}0 & 2 & 1 & & & & 3 \\ 2 & 0 & & 1 & & 3 & \\\3 & & 0 & 2 & 1 & & \\ & 3 & 2 & 0 & & 1 & \\ & & 3 & & 0 & 2 & 1 \\\1 & & & & 3 & 0 & 2 \\\& 1 & & 3 & 2 & & 0\end{array}\right] .$$
Prove that no two integers in \(Z_{n}\), arithmetic mod \(n\), have the same additive inverse. Conclude from the pigeonhole principle that $$\\{-0,-1,-2, \ldots,-(n-1)\\}=\\{0,1,2, \ldots, n-1\\} .$$
