Britney Gallivan Britney Gallivan Britney Crystal Gallivan (born 1985) of Pomona, California, is best known for determining the maximum number of times that paper or other materials can be folded in half. In January 2002, while a junior in high school, Gallivan demonstrated that a single piece of toilet paper 4000 ft (1200 m) in length can be folded in half twelve times. This was contrary to the popular conception that the maximum number of times any piece of paper could be folded in half was seven. She calculated that, instead of folding in half every other direction, the least volume of
Folded Reed–Solomon code Folded Reed–Solomon code In coding theory, folded Reed–Solomon codes are like Reed–Solomon codes, which are obtained by mapping formula_1 Reed–Solomon codewords over a larger alphabet by careful bundling of codeword symbols. Folded Reed–Solomon codes are also a special case of Parvaresh–Vardy codes. Using optimal parameters one can decode with a rate of "R", and achieve a decoding radius of 1 − "R". The term "folded Reed–Solomon codes" was coined in a paper by V.Y. Krachkovsky with an algorithm that presented Reed–Solomon codes with many random "phased burst" errors . The list-decoding algorithm for folded RS codes corrects beyond the formula_2
