 	\begin{align*}
 		\text{AND} &= \lm ab . (a~b~F) = \lm ab . aba \\
 		\text{OR} &= \lm ab . (a~T~b)  = \lm ab . aab \\
 		\text{XOR} &= \lm ab . (a~ (\text{NOT}~b) ~b)

-	It may be worth mentioning that OR $= \lm ab.(M~a~b)$ is also a solution.
+	Another clever solution is $\text{OR} = \lm ab.(M~a~b)$
