Thread for your unsure discoveries

[johamwit]

I've tried quite a lot of different glider collisions against this pattern, and so far I haven't found one that destroys it. Does anyone see an obvious way to break it?

I don't understand. I've tried a few gliders, just to check. All glider collisions destroyed the pattern.

Would you kindly show us a glider collision that does NOT destroys the pattern ?

[johamwit]

Perhaps it's just a matter of terminology, and what you mean is a single-glider collision that not only “destroys” the pattern, but kills all the cells in it, leaving no survivors or descendants.

There are a lot of patterns that can be killed with just one glider. If the pattern exhibits periodicity in one direction, then it's called a fuse/wick. Examples of patterns erased by glider collisions can be found too in those large spaceships that “move” by creating a copy of themselves in another location, via construction arms, and then erase the previous instance.

[higumachan]

Sorry, I worded that very badly. What I meant to say was that I think I may have found a pattern that cannot be destroyed by **two gliders**, but I failed to include the word "two" in my post.

Also, by "destroyed" I didn't mean that an individual glider collision has to leave the pattern unchanged. I meant *glider destruction* in the sense used here:

https://conwaylife.com/wiki/Glider_destruction

In other words, I suspect that this may be a still life for which no two-glider destruction exists.

Sorry for the confusion.
