### Seeds

I found a wick that moves at 16c/8 in other words 2c, so maybe the speed of light is NOT the speed of light

I don't understand how it's impossible. I'm pretty sure a wick can move at c/2 in seeds.

The search stopped caring about any other possible branches of the tree once it stumbled on the one above, so maybe there could still be a width 18 bilaterally symmetric c/6 spaceship...

More excitingly, here's a long c/7 partial at width 15 with odd bilateral symmetry:
`x = 59, y = 15, rule = B2/S53bo\$11bo4bobo6b4o14bo10bo2b2o\$3bo2bo5bo3bobobo5b2obo8bo13b3o2bo\$2bo7b3o5b2obo9b2o5bo7bo\$16bobo6bobo5bo2b3o4bobo2b3o5bo\$o7bo2b2o2bo3bo5b3o3bo10bobo6bo3b2obo\$5bo13bo5bo4b3o4bo3b2obo6bo5bo\$5b3o3b5ob2obo5b3o13b3o\$5bo13bo5bo4b3o4bo3b2obo6bo5bo\$o7bo2b2o2bo3bo5b3o3bo10bobo6bo3b2obo\$16bobo6bobo5bo2b3o4bobo2b3o5bo\$2bo7b3o5b2obo9b2o5bo7bo\$3bo2bo5bo3bobobo5b2obo8bo13b3o2bo\$11bo4bobo6b4o14bo10bo2b2o\$53bo!`

The first 55 rows reappear unmodified after 7 generations, which I think is pretty good. Also, the top band of 3 rows is at a very weak connection - only one generation of actual interaction, and since it's at generation 6, basically any other single gen interaction that prevents any birth at all in that region will work fine.

That c/6 is great. It might be possible to make a p5 gun that shoots the necessary spaceships to push it along. I don't think this is likely to be found, but it would be cool.

According to this: viewtopic.php?f=11&t=2192

There is a p4/c1 glider+garbage generator that I published in 2000. Here you are:

`#CXRLE Pos=0,0x = 10, y = 2, rule = B2/S4b2o\$2o6b2o!`

Jason Summers has a pattern collection on his website which includes some oscillator collections. In the file "oscs-p002.lif" there is an extended oscillator which is comprised of a variety of wicks all joined up in a circuit - It includes four segments of this wick joined to several different wicks. I don't actually see examples of fenceposts for any of the wicks in the circuit, but I'm sure they could be found.

I posted a collection of p2 patterns for Live Free or Die over several posts which include various oscillators that incorporate some of the wicks which exist in Seeds. I don't think I spent a lot of time searching for fenceposts for any of the wicks other than the "lever wick" but I'm sure they exist. However, it's very possible that they won't be small so quite a broad search would be needed to find them. Whether my experience searching in lfod translates to Seeds, I can't say.

There certainly is and it would be the tool to use, though Nicolay Beluchenko's version might be more suitable because it will prune the search branches which explore the depths of all possible combinations of the p2 checker.

Garden of Eden:
`x = 3, y = 3, rule = B2/S2o\$3o\$3o!`

Proof:
Because in this generation these cells are on, they must be off the generation before, as they cannot survive:
`Generation 0:▓▓░▓▓▓▓▓▓`

`Generation -1:░░?░X░░░░`

But cell X must be on in generation 0, but it can only get one on neighbor, the question mark, therefore, this pattern has no predecessors.
