Cis-snake-tie

From LifeWiki
Revision as of 23:27, 19 November 2023 by Dvgrn (talk | contribs) (Undo revision 141291 by Confocal (talk) It does certainly seem like a good idea to coordinate changing the LifeWiki and Catagolue, roughly at the same time. However, removing a *proposed* move tag -- especially for the second time in a row, for the same exact reason! -- seems like a step in completely the wrong direction for getting those coordinated changes made.)

The cis-snake-tie is a 12-cell still life.
