Use carrier {0,1} and read rows as the left operand:

0 1
0 1

Thus x diamond y = y. The premise reduces to y = y for every x,y. For
x=0 and y=1, the target has left side 1 and right side 0, so it fails. The
unique one-element operation satisfies the target, proving minimality among
nonempty carriers.
