Four new rules with replicators

neighbor counts, like Life) that have self-replicating patterns in them.
They are: B358/S23467, B37/S345, B3568/S2347, and B357/S3458. For details

It would be helpful to non-experts if you included a link from this webpage
to a webpage explaining your CA-rule notation, so that they would not have
to deduce its meaning from context...

... but the B/S notation is _the_ standard for two-state totalistic
rules.

And would a non-expert in CAs happen to know that fact? ,:-|
Interest in CAs does not imply _expertise_ in CAs, nor knowledge
of the existing literature-base on them. Like most NGs, the lurkers
here probably outnumber the posters by at least ten to one, and
there are probably a number of newbies who have stopped by merely
because they've just read about CAs in a novel or article somewhere...

I agree with Gordon that it should be possible to understand my web pages
without already being an expert in CA's, so I have added a page describing
the notation as he requested.

Of course not, but someone clever enough to have an interest in cellular
automata should be resourceful enough to research the meaning of the
notation pretty easily.
It never hurts to explain notation, but I certainly wouldn't dock him
points for not documenting a standard, universal notation.

I don't feel I was ``docking him points'' --- I was attempting to suggest
a small improvement to his webpage.

This is a problem for most non-trival subjects.
A lexocon will devlop but the FAQ (if it exists at all)
will lack a glosery. Will a lurker understand what GOE* is?
Some selfless sole, who can spell, should take it apon themselves...
Line noise.

Replicators seem to be one of the more common patterns generated from
a random soup when applying rules from the 'Weighted Generations'
family included with the new version of 'Mirek's Cellebration' which
you can download here:
