Bowling green the sun when playing. In cities, where outdoor space is limited, greens are rarely 40 metres in length (however, they are generally still square). It is not unusual to find greens that are rectangular in shape. On rectangular greens games are played in one direction only. The length of a rectangular green is still between 31 metres and 40 metres. The width can vary from as little as 8 metres (enough for one rink) to as much as 60 metres or more. The width of a rink for outdoor play will be between 4.3 metres and 5.8 metres (for indoor
Maximum length sequence Maximum length sequence A maximum length sequence (MLS) is a type of pseudorandom binary sequence. They are bit sequences generated using maximal linear feedback shift registers and are so called because they are periodic and reproduce every binary sequence (except the zero vector) that can be represented by the shift registers (i.e., for length-"m" registers they produce a sequence of length 2 − 1). An MLS is also sometimes called an n-sequence or an m-sequence. MLSs are spectrally flat, with the exception of a near-zero DC term. These sequences may be represented as coefficients of irreducible polynomials in a polynomial
