Bowling green edges of the green dropping off towards the surrounding ditch. Other greens are generally as level as possible. Several games of bowls can be played on a bowling green at the same time. The number of games depends on the dimensions of the green. Each game is played on its own portion of the green. These divided portions of the green are called rinks. The length of a green in the direction of play will be between 31 metres and 40 metres. The green should have a suitable level playing surface made of grass or of an approved synthetic material.
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
