Greek letter "Pi' (3.14) within a meander pattern Trucker Hat

The Greek letter 'pi' is surrounded by a meander pattern, the inner circle of which is made up of the first 200 digits of the pi constant! A perfect gift for Greeks, lovers of Greece, mathematicians, scientists, classicists, or just for fun on pi day and beyond. You may edit the colour of the design. The mathematical constant of 'pi' from Euclidean geometry is the ratio of a circle's circumference to its diameter, and is symbolised by the Greek lowercase letter 'pi'. It is also referred to as Archimedes's constant. It is an irrational number and a transcendental number. In this design, it is within a meander pattern, a very common ancient Greek decorative device.
