For the listed g.f.: (1 + xy + x^2y^2)/(1 - x - y + xy - x^2y^2) in
A099172, expanding to series does not seem to generate the terms of the
array. Maybe I am doing something wrong on my end, but could someone please
check it and make any necessary corrections (and let me know)?

Thanks,

Ed Jeffery
