    I have tried to streamline this entry, for instance in moving the remark on “unshuffles” out of a superfluous subsection and right into the Idea-section, and in collecting all variants of stating the definition right there in the Definition-section.

    I have created a “Properties”-section (now here) and added to it two subsections that used to be at product of simplices (but don’t say anything directly about simplices):

    “The poset of (p,q)(p,q)-shuffles” and “The Anti-Lex order”.

    Both these sections leave room for streamlining. Also, their graphics remains broken, and have been for a long time (already when we discussed this last time here)
