%N Number of toothpicks and Dtoothpicks after nth stage in the Dtoothpick "narrow" triangle of the third kind, second version.
%C The structure is essentially the same as A220522 but here the borders do not contain Dtoothpicks with exposed endpoints except the initial Dtoothpick. The structure is one of the oblique wedges of several Dtoothpick structures. For more information see A220500. The first differences (A233763) give the number of toothpicks or Dtoothpicks added at nth stage.
