||The pattern does not fit well in the infobox. Suggest to put the pattern back in the main text (to be able to make it displayed larger in some reasonable way), and either decrease size of the infobox or hide/remove the infobox entirely.

Spiral growth is a self-constructing pattern built by Dave Greene in August 2014 that uses four universal constructors (UCs) arranged in a diamond to build four more UCs in a slightly larger diamond. This was the first B3/S23 pattern that exhibited spiral growth.
Much smaller versions have now been assembled using the single-channel construction toolkit. The version shown in the infobox was constructed by Dave Greene in June 2017.
