Such behaviour has been known previously in non-totalistic rules in which patterns of a higher symmetry explode, but rapidly stabilise if an element of asymmetry is introduced. This implies that there exists some sort of subtle "symmetry" which is preserved by these explosions, and foreign bodies which violate this symmetry result in interactions that forbid the explosion from proceeding.muzik wrote: ↑November 17th, 2020, 7:28 pmEDIT2: VERY bizarre - it appears there's some hidden crystal structure within that allows these to explode, but outside material can disrupt this and collapse such an explosion.Code: Select all

Using the following lifeviewer demos, such an explosion can be initiated from within the pattern via adding a single cell - in this case, at position (5, 0). Note how the generation in which the cell is added matters (the first stops the explosion, the second does not) - this is very likely due to the nature of the "checkerboard" neighbourhood, which effectively alternates every two generations:
