Thread for your unsure discoveries

[Vort]

Dieter and Peter's glider gun collection article mentions
"the collection is actively updated whenever a smaller gun on a particular period is discovered".
There gun_8256 exists, which have area of 2744 cells (49x56).
I found smaller gun with the same period with area of 2142 (51x42).
Please recheck it (I'm new here and not sure if I made it correctly) and update database if it is fine:

To submit, put the RLE in http://catagolue.hatsya.com/syntheses and click "Post" (it works for glider guns too even though it says syntheses). I believe you'll need to remove the history cells, but I'm not sure.

4-digit gun periods aren't well-maintained, so it's quite likely yours is a true reduction.

It will update in slightly over an hour (16:20 UTC), assuming you get it in before then.

There is a reaction involving a boat and a glider, where the boat is destroyed cleanly and the glider is reflected 90 degrees.

but could someone turn it into a glider reflector (and call it the fite reflector) please?

edit: unrelated, but cant people just chain all the blockic reflectors onto eachother so that we dont have to put them seperately?

Obtained from the p363, by doing a trombone slide adjustment and replacing a Snark with a Snark64:

[...] What's the smallest resettable loop with a multiple-of-8 period?

[...] EDIT: Other good options, p363. Nice amount of space but not a direct Herschel:

H + House Siamese Shillegah + Block = U turner + glider + Weird still Life

[...] H + House Siamese Shillegah + Block = U turner + glider + Weird still Life

That reaction is involved in a known glider synthesis for that weird still life (xs20_ok4mp3z6943), which currently can be seen in the section "Glider synthesis" of the Catagolue object page:
