Good monring Robert and Neil,
For the broken Tittmann links in
A003763, A222200, A222201, A222204
the file is stored in the Internet Archive:
I cannot find the link in
A201511: Peter Tittmann, Polynomials of nxn Grid Graphs
So if you write, please ask for the 2nd link also.
I could write to Prof. Tittmann if you want.
The broken link problem is permanent, but *not hopeless*.
From the 400,000 links in the OEIS I count 21872 unique
ones, and of them currently 2595 do not pass my tests.
For details and the current status of that small project you may look at
Best regards - Georg
