**quincunx**(IPA ['kwɪnkʌŋks] ) is the arrangement of five units in the pattern corresponding to the five-spot ondice ,playing cards , ordomino es. The quincunx was originally a coin issued by the Roman Republic c.211-200 BC, whose value was five twelfths ("quinque" + "uncia") of an as, the Roman standard bronze coin. On the Roman quincunx coins, the value was sometimes indicated by a pattern of five dots. Typically, a modern quincunx consists of five objects arranged in a square, with one object at each of the square's four corners and the fifth in the square's center. If the four corner objects form a rectangle, the pattern is still considered a quincunx.The significance of the quincunx pattern originates in Pythagorean mathematical

mysticism . This pattern lies at the heart of the Pythagoreantetraktys , a pyramid of ten dots. To the Pythagoreans the number five held particular significance and the quincunx pattern represented this significance.fact|date=May 2008**Examples**Quincunx patterns occur in many contexts:

However, samples at the corner points are shared with adjacent pixels, so the number of samples needed is only twice the number of displayed pixels.
