Making a c/6 orthogonal puffer

[Sphenocorona]

Now, at this speed the ships available have more fragile and weaker sparks, but there is also more than one ship available for use. The three ships that are likely usable are the dragon (weak side sparks), and the un-named spaceships 56P6H1V0 (isolated dot sparks under its "wings") and 114P6H1V0 (very strong forward spark and a usable domino side spark). Gliders are also able to be used for re-ignition as it takes these ships two generations longer to travel forward one cell than gliders.

I haven't tried searching for any collisions yet, but the 56 cell ship should be excellent at the front for converting the standard ships into something workable.

I had already tried the same approach that I had used for building 2c/7 puffer, before you created this thread. I ran a gencols search colliding each of standard spaceships with two of c/6 spaceships in all combinations, but found no useful sparks. But I may have missed something.

Here's a near 2c/12 ship that has a strong back spark - although the partial is probably easily completed (I know for a fact that the partial can be extended further) I have no idea if it can be completed with the pre-TL production intact:

Code: Select all

x = 30, y = 23, rule = B3/S23
4$20b2o$9b2o2b2obo2b3o3bo$5b4o4b2o2bo2b2o3bo$4bo6bo2bo2bo5b3o$3bo3bo3b
o3bobo5b3o$7bo8bo8bo$4b3o2bobo5bobo3b3o$8bo3bo3bo3bo3b2o$4b3o2bobo5bob
o3b3o$7bo8bo8bo$3bo3bo3bo3bobo5b3o$4bo6bo2bo2bo5b3o$5b4o4b2o2bo2b2o3bo
$9b2o2b2obo2b3o3bo$20b2o!

The most striking fact is that the back is a solid line, and it almost perfectly re-appears. Repairing the line but leaving the pre-TL will show how close it is to being a ship already.
