Japanese Mahjong Japanese Mahjong Japanese Mahjong (Japanese: 麻雀, 麻将 or マージャン; "mājan"), also known as Rīchi Mahjong, is a variation of mahjong. While the basic rules to the game are retained, the variation features a unique set of rules such as "rīchi" and the use of "dora". The main mahjong article contains general terms, but only English and Japanese terms are used here. Terms like "chow," "pung," and "kong" are not used in this variation, yet their functions are still used. Instead, they are referred to in Japanese as "chī", "pon", and "kan". In 1924, a soldier named Saburo Hirayama brought the
Bloch's higher Chow group localization sequence). Bloch's higher Chow group In algebraic geometry, Bloch's higher Chow groups, a generalization of Chow group, is a precursor and a basic example of motivic cohomology (for smooth varieties). It was introduced by Spencer Bloch and the basic theory has been developed by Bloch and Marc Levine. In more precise terms, a theorem of Voevodsky implies: for a smooth scheme "X" over a field and integers "p", "q", there is a natural isomorphism between motivic cohomology groups and higher Chow groups. Let "X" be an algebraic scheme over a field (“algebraic” means separated and of finite type). For
