Report on the "continua" problem.
I have edited A073120, A057102, A009112 and I added
the missing A256418 and transferred most of the old A057102
to the new entry.

Unfortunately, A057102 was mentioned in a lot of other entries,
and (as Maximilian points out) these all need to be checked.
The sequences in question are A003273, A135789-A135794,
A135796, A135797, A057103, A057105, A056203.
At present all I have done is to add a comment (which can later be removed,
of course), saying that because they refer to A057102 they should be
checked.
If anyone can help by checking these entries, please do so!

Best regards
Neil
