This is the star graph S_{1,1,3}
It almost certainly has another standard name. That would be useful.
It can be found at: http://www.graphclasses.org/smallgraphs.html#X172
HOG says: "Graph with canonical form 'E?NO'

Closing this issue.
NOTE: No values will have been precomputed for has_fork
or is_fork_free
as part of Issue #551. We branched precomputing off prior to this commit.
hi,
the chair has order 5, while the "fork" (i must have seen this in the literature) has order 6. we settled on Star_1_1_3 (the name on the Graph Classes website.
this graph is also the "killer" and the "milkbone"
:)

I understand this issue is closed, so ignore this. But for posterity, I have always known this graph as the chair.

The graph
fork
is poorly named, since there's a function with that name. And, depending when things are loaded,fork
doesn't reference the graph.The functions
has_fork
andis_fork_free
are not included in any list of properties. They probably don't have any precomputed values either.
