三つ巴 refers to a three-comma emblem or a three-way fight. 四つ巴 is the four-party version, less common but follows the same pattern.
Compound of 四つ (yotsu, 'four') + 巴 (tomoe, 'comma-shaped design'). The metaphorical sense of a multi-party struggle comes from the intertwined, balanced arrangement of the tomoe in the emblem.
