To make a low this time, you have to use the 7-3-A combination from the board. Since you need an Ace and Trey from the board here, you cannot use either the Ace or Trey from your hand, but must use the 4-2 combination instead. Your low is therefore 7-4-3-2-A.

Here all four of your hole cards also appear on the board. Despite this duplication you can still make a qualifying low. For example, you can take the 3-2 combination from your hole cards and put it together with the 7-5-4 from the board to make a 7-5-4-3-2 low. Fortunately, there are still two unduplicated hole cards when you combine your two required hole cards with three from board.
