Soddy's hexlet by Wikipedia Bot 0
Soddy's hexlet is a configuration in geometry involving three circles that are tangent to each other in a specific way. Named after the British chemist Frederick Soddy, who explored this arrangement in connection with the theory of circles, Soddy's hexlet refers to the construction of two smaller circles that are tangent to three larger circles, along with two additional larger circles that touch the three originals.
