Number: Real multiplication tables

Your mission, should you choose to accept it, is to find and build groups of identical collections. Both the number of objects per collection, and the number of collections in the group, must be iconic numbers. For example, there are sixteen chess pieces on each of the two sides of the board – an iconic two-by-sixteen. The four seasons each have three months for an iconic three-by-four. Cerberus the three-headed dog had two-by-three eyes.
