An interesting rule. Most patterns are methuselahs, even very small ones, and it's difficult for cells to die.
There are three very interesting patterns I've found so far:
"Fish", a c/4 elementary glider.
"Shoot", a pattern that duplicates every 4 pixels.
"Pillar", a massive pattern that duplicates every few hundred pixels.
The right shape in the RLE forms "Pillar" after several thousand generations.

We don't usually create new threads for rules unless they prove interesting enough; you can share results at Thread For Your Unrecognised CA. Aside from that, the name Coral is already reserved for B3/S45678; if you ask me, I think the large-scale texture is more similar to a brain with Alzheimer's disease.

Ok. thanks. I'll move it, and update the RLE (i found a new oscillator)
