However, the same isn't true whatsoever for the period-71 glider gun design, as the Snarks are shifted 3 cells out diagonally between the period-69 and period-73 glider gun designs (adding 24 more generations to the glider loop's period (with only one glider instead of seven) from p414 to p438) - attempting to add 12 more generations to the loop's timer (p426) to achieve a period-71 glider gun would require shifting the pair of Snarks out by 1.5 cells diagonally, thus giving an extrapolated bounding box of 83.5x66x5... which would've been larger than the current smallest period-71 glider gun design (78x59) anyway.

In terms of other periods, 5n periods still lacking include guntrue_1065, guntrue_1045, and guntrue_1025

Notice that the period septupler can be moved diagonally one cell closer to the p151 gun, assuming an appropriate weld can be found (which indeed it can). The easiest way to do this is with JLS. Very briefly, the process looks something like this:

1. Open JLS, set the size to 50x50, the period to 25, and set "after last generation is..." to "unknown". Then set the whole grid in generation 0 to OFF.
2. Copy and paste the following pattern into JLS and select "Search->Accept displayed state":

   Code: Select all

   x = 44, y = 36, rule = B3/S23

   bo$7b2o!

3. Select the regions containing the stator cells of the welded catalysts and press the "1" key to set them as period 1. Do not select any of the rotor cells during this process. You may need to do this multiple times, depending on the shape of the stator.
4. Clear all of the period-1 (yellow) cells.
5. Select the rightmost catalytic reaction and move it diagonally up and left by one cell (use ctrl+shift+arrow keys).
6. Run the search to see if there are any solutions.
7. If there is a solution, restart the search, adjusting the population limit (under the "constraints" tab of "Search->Options...") until you find the minimal solution.

In this case, the above process gives the following weld, shown here as part of the complete p1057 gun:

Thanks Sokwe. Alas, I currently have no life software set up on my new computer, nor do I currently have time to install it (school, ugh).

Somewhat related, this is my best pass at the last even period below 1100 not in catagolue (guntrue_1042), but here the problem is more of a fitting issue than a situation where a weld is needed. Posting if anyone wants to try increasing compression or row shaving.

Edit #4: Wait, the third and fourth "reductions" I posted are a different period gun, gun_553. It might be possible to beat that record with a little rearranging (current gun_553 record: 4956 cells).
