Expression: The grid with five Xs in a column at the leftmost part and fifteen Xs in total

The target grid has a distinct pattern of five Xs aligned in a column on the left side, with a total of fifteen Xs filling its cells. This configuration sets it apart from the first distractor grid, which has the Xs positioned in the middle column and the second distractor grid, which has the Xs in the rightmost column.
