Schläfli double six

名詞

(geometry) A configuration of 30 points and 12 lines. The lines can be partitioned into two subsets of six: each line is disjoint from (skew with) the lines in its own subset of six lines, and intersects all but one of the lines in the other subset of six lines. Each of the 12 lines of the configuration contains five intersection points, and each of these 30 intersection points belongs to exactly two lines, one from each subset.

日本語の意味

（幾何学）30の点および12の直線からなる配置。12本の直線は、各自のグループ内の6本の直線とは互いにスキュー（交わらず）であり、対向するもう一方の6本の直線のうち1本を除く全てと交差する。各直線には5つの交点があり、その各交点は互いに異なる2本の直線に属する。

The Schläfli double six is a classical configuration in algebraic geometry, comprising 30 intersection points and 12 lines with each line meeting five points and each point lying on exactly two lines from opposite sets.
