Revision as of 23:17, 13 May 2024 by DroneBetter (talk | contribs) (make c/2 row entirely green! (thank you very much to my friend wwei23 for their JLSery))
This page is an equivalent to the Spaceship Search Status Page, albeit for 2x2 instead of Life.
Known spaceships by width
The majority of spaceships shown as upper bounds are from LaundryPizza03's updated version of David Eppstein's glider database.[1]
The first four rows are by AforAmpere, all subsequent expansion thus far is by DroneBetter, Darren Li (enlisted for increasing 3c/7 to logical width 12 and 2c/7 asymmetrical to width 10) and wwei23 (for their ability to use JLS, which apparently utilises some manner of dark magic seeing widths far beyond those of qfind at low periods and high speeds)
all results were found with qfind except where noted otherwise

Note by DroneBetter: From the previously-included (1,1)c/3 entry, it appears that unlike LifeWiki:Spaceship Search Status Page (which considers the maximum orthogonal width of the pattern itself), this page measures diagonal spaceships by the number of cells in an orthogonal ray through the footprint left in their wake (corresponding with half-diagonals of width perpendicular to travel direction). The other diagonal speeds are measured accordingly.
| Spaceships of speed c/2, 2c/4,[3] 2c/5, c/3, 2c/6,[3] c/4, c/5, c/6,[3][4] c/7,[5] 2c/38,[6] (1,1)c/8, (1,1)c/4 and (1,1)c/3. (click above to open LifeViewer) |
Notes
- ↑ these were found with JLS,[2] qfind cannot reach beynd logical width 14
- ↑ was found by Josh Ball on November 5, 2015[3], width 26 has been disproven with qfind but it crashes at 28, so not guaranteed to be of minimal length, but is of minimal width so counts as a green
