I suspect this will be substantially more difficult than 2c/4 searches since there are comparatively few known short, wide 2c/5 ships.

The chasm between 2c/4 and 2c/5 has never been more apparent to me than now, at the end of an awful lot of searching. Indeed, the paucity of ending arms hurts greatly, but also the trick of reducing the period to c/2 and solving that is gone and the searches are just so much slower and fill memory and die so much faster. For all my work I do not have much to show...

My main attack was to search the wick back-to-front looking for a split. I wrote a new tool/hack to notice some splits automatically in a search since spotting them in random partials myself seems wasteful and poor. Many showed up and I tried quite a few side-to-side searches to turn them outwards. Several splits were vaguely viable, but ultimately nothing I could resolve.

The best looking split ("split A") I gave up at here:

All best partials stitched together in all generations, unsolved branches marked with exclamations:

I was only able to solve one branch at any point in all my work and it is that one side-to-side branch solved there. Even that required another tool/hack to look for completions from a database of known arm endings which itself was built from the collection of 2c/5 ships in jslife-moving. The other two side-to-side branches seemed generally viable in that the partials are always quite long, but just never seem to solve. The back-to-front also seems so live, but it just never ends. Shown is the last/deepest version of it I was looking at, having "single branch" moved the search forward several times when the connection looked very thin.

The second-best looking split ("split B") and turn pair was:

I searched a good bit here as well, but none of the branchings seemed as good as those found on split A and so I spent most of my time there.

I have one more dirty trick still in progress. It tries to split the center in a way that the two sides of the split are the same (but off-phase, similar to how the two sides of the wick are the same but off-phase). If it works it would mean only one "half" to solve instead of two, but it's not clear it will and given that I can't even solve one half of my own choosing from all the previous searching I'm not very optimistic even if it does work. If I post nothing further in the next few weeks you can probably assume it didn't work out.

The best looking split ("split A") I gave up at here:

This is quite impressive, even if it's not yet particularly close to completion. It certainly looks like this idea has potential, but I'm not surprised that it's been challenging so far. Here's an alternate stabilization of the completed arm that allows a bit more room for extending one of the side-to-side arms:

Excellent. Does your completion database incorporate the ships in the knightt search results collection? (note that in addition to the 2c/5 folder there are some width-13 2c/5 ships in the "incomplete" folder)

It does not, yet. The code that parses and analyzes to build the DB is so slow I'm gonna have to invent a way for it to save its results before I can swallow that I'm pretty sure (right now it loads raw files and analyzes at the beginning of every search configured to use it).

Trying to solve it more directly but still allowing it to eat into the sides a bit there are some very long partials even at very small widths (GS even), but nothing that finished. Longest for the biggest search I ran like this:

Period-dividing to c/2 (even) is solvable, but like most c/2 solutions is hard to make small, e.g. the first thing I could cobble together:

It was used in my var-524+24n.lif rake from 2001 in Jason's collection.

As usual, it's just the first pick of branches and pieces that I could get together and I have spent no time optimizing it.

April 10, 2022. I found it. There wasn't a new search program. I was manually searching through sparked Puffer 2s and stumbled across this spaceship.

Solved the back-to-front branch with a bunch of choking down and two subbranches, both solved by that same completion database hack.

The following might be one step forward and two steps back on the 2c/5 wickstretcher partial. I tried a different branching, but now there are 3 additional incomplete branches. It should be possible to complete the front-to-back branch reasonably easily, but I'm not sure about the side-to-side or back-to-front branches:

An alternative idea is to combine the front-to-back and side-to-side branches into a single front-to-back branch. Here's a partial result that has a bit of a branch, but one of the branches might be too close to the wick for this branching to be useful:
