It appears that this sequence ("Number of walks from NW corner of n X n 
array to SW corner.") is only counting walks that include every cell of 
the array exactly once.  Can someone verify this?  (I can't read either 
German or Chinese.)

It would also be useful if someone who does read German could come up 
with page number(s) for the link to the Moebius work.
