the basic idea (taken from other guns, such as gun_598) is to fire a glider stream into a bunch of period-multipliers, reflecting the last one back at the original stream to remove one glider before it can enter the period-multiplier, thus resulting in a period of [gun_period] * [what the multiplier would have been + 1]

gun_280 reduction (1408 -> 1344) via swapping a sparker to pull in the quadri-Snark further:

Code: Select all

If you're investigating p5 sparkers to reduce p55-type guns, perhaps guntrue_165 can also get something to fix the BB glitch?

EDIT:

gun_255 reduction in the spirit of the p245 (2263 -> 2090)

255 is actually broken - real BB is 2409. This is a reduction, and I always love a fix to a broken BB gun

EDIT: gun_260 in a similar vein (2346 -> 2208) - there may be a sparker that can weld with the eater to reduce it further (sorry, super cool dependent-loop gun!)

Alas, on the other hand I do lament that this period was represented by said cool dependent reflector-based gun (below for reference)

Topic 2. The 3pi-to-G used in (for example) gun_663 can be filtered by a sparker to be a (3n-1)pi-to-G. With a 2-glider pi synthesis this can reduce some guns with period multipliers 5 and 11, especially those that are too low-period to work with the standard x11 multiplier.
