I've used the following command to get correct values of A095268 for n up to 7:
wget -O - "http://theory.cs.uvic.ca/per/nump/numpart.pl.cgi?program=DegreeSequences&n=7&k=0"
| grep "TD ALIGN" | grep -c -v 0
But for n>=8 the server returns only a part of the partitions with an error:
Oops: You asked for more objects than the current limit of 1000.
