Seqfans,
Could someone extend sequence: A095268
"Numbers of distinct graphical partitions corresponding to graphs on n=1,
2, ... nodes."
With offset 0, A095268 begins:
[0, 0, 1, 2, 7, 20, 71, 240, 871, 3148, ?]
The self-convolution square-root of A095268 (with offset 0) begins:
B = [0, 1, 1, 3, 7, 24, 75, 264, 917, ?]
I wonder ... do the terms of B continue to be integer?
Since a g.f. for A095268 is not known, it would be interesting
if the trend continued for more terms.

Thanks,
