Is this c/10 spaceship known?
That's a beautifully concise numbering system for sharing being used there.Now if only we had descriptions of chemistry that were this terse.  Imagine if this kind of problem solving, collaboration, simulation, and instant verification were the norm for synthetic chem.  One of the comments -- "[Let's] use gencols to rub the ship against gliders and *WSSs to see whether there is a useful collision to maybe build a puffer" -- just blew me away.  If this were chemistry, that commentator would have been suggesting automatic nanomachine factory discovery.(InChI appears to be close.   But vast amounts of data are locked up in obtuse formats are either Assigned-Names-And-Numbers style formats which are useless to indexing and similarity searches, or formats that embed non-relative coordinates in 3d space, etc, in such a way that computing a deterministic ID for sharing is practically a nonstarter.)
