Re: Thread for basic questions

I'm looking for a good definition of stabilize/stabilization. The term is used all over the place, we all know what we mean by it, but I have not come across a well-thought-out definition.

Snarkmaker article says 2428 gliders; Book (B.2) says 2427. Truth?
Both of the actual statements are true. The Snarkmaker article includes

"1 glider (suppressed by a single cell) showing where a second Snarkmaker recipe could be safely appended".

I'm pretty sure the fourth number is a hash value based on the population change between generations. This is how it's the same each time even if it appears on a different generation.

Victory! Brilliant! What was it and how did you figure it out?
I searched the Chrome bug reports for recent reported issues and found one that looked similar. The report had a test case and potential workaround so I tried that and it worked.
