| 单词 | Solomon's Seal Lines |
| 释义 | Solomon's Seal LinesThe 27 Real or Imaginary straight Lines which lie on thegeneral Cubic Surface and the 45 triple tangent Planes to the surface. All are related to the 28Bitangents of the general Quartic Curve. Schoutte (1910) showed that the 27 lines can be putinto a One-to-One correspondence with the vertices of a particular Polytope in 6-D space in such a mannerthat all incidence relations between the lines are mirrored in the connectivity of the Polytope and conversely (DuVal 1931). A similar correspondence can be made between the 28 bitangents and a 7-D Polytope (Coxeter 1928) andbetween the tritangent planes of the canonical curve of genus four and an 8-D Polytope (Du Val 1933).
