Heraclitus and Licetus (90/75 km) are two stuck together craters, but they are more complex than you think. The shape can confuse you because these are some overlapping craters. From what I can tell, Heraclitus is the oldest of them. If you remove craters are overlapped over it, you will see that this is a circular crater affected by many small impacts. Over it, were held two impacts: one to the north that formed the crater Licetus, and one to the south, called Heraclitus D (52 km). Images are upside down for better observation.
Circular crater to the southeast of Heraclitus, the Cuvier (75 km), which is sticking to the edge of Heraclitus.
