A 66-sided polygon is called a hexacontakaihexagon. The name is derived from the Greek prefixes "hexaconta-" (meaning sixty) and "hexa-" (meaning six), along with the suffix "-gon" (meaning angle). The interior angles of a hexacontakaihexagon sum up to 11460 degrees, calculated using the formula (n-2) * 180, where n represents the number of sides.
