It looks like it should be

a domino with 5 pips on the left and 6 pips on the right

because

if you view each row of dominoes as a single six-digit number and perform subtraction, you get 524601 - 363245 = 161356.

    $\begingroup$ @PDT agreed this answer is great. Reddit has a lot of good places for iq test related puzzles where there is a good reception for challenging questions and well thought out responses to them 😃! $\endgroup$ Commented Feb 20 at 4:03
