I can tell that they&#x27;re different, but the differences are really subtle in large groups of them.<p>Numbered left to right, top to bottom.<p>2,4,6,7,9 look close enough that I probably wouldn&#x27;t be able to guess which one it was if I only saw one of them at a time.<p>1,3,11,12 looks similar, I might be able to tell the recognize 3 and 11 on their own.<p>10 looks similar to the 2nd group, but is different enough that I could probably pick it out.<p>5 and 8 are unique enough that they stand out by themselves.
