The shorter form is asymmetrical, having lost part of the symmetry of the original form. But the evolution remains symmetrical with respect to the long empty line in the center. So, wouldn't there be another form constructed from the two bottom halves of the displayed form? It doesn't look like they would interact with each other either. How would that affect the size of the bounding box and the cell count?
- You're quite right, that creates a period 7 oscillator with 86 cells, which is smaller than the given form. Considering that bottom component was found in the 70's, I'd imagine it goes by another name, but I don't have any archives or any such thing that goes back that far. Perhaps we should just add it to the image gallery for now? Nathaniel 14:54, 11 September 2009 (UTC)
For the sake of completeness and cross referencing, it would be nice to include this third image; perhaps it could simply be called 86P7 until someone claims it. — Preceding unsigned comment added by Spam User (talk • contribs)
