I assume only "nontrivial" methuselahs (methuselahs you can't just adjust trivially and get something which lasts longer) are counted

The easiest example would be shooting a glider at a block or blinker and trivially lengthening the lifetime by moving the glider back some number of generations.

Another example would be having a glider from an R-pentomino strike a distant (far enough away so that they don't interact except via gliders) block or blinker and simply moving the block or blinker farther away from the R-pentomino along the same diagonal.
to lengthen the lifespan of the methuselah in a way that can lengthen its lifespan indefinitely without any additional effort/rigor per generation lengthened
Define "effort". Your definition is even more subjective than the word "trivially."MathAndCode wrote: December 10th, 2020, 12:02 amto lengthen the lifespan of the methuselah in a way that can lengthen its lifespan indefinitely without any additional effort/rigor per generation lengthened

That is why I typed additional.

Oh wait, we are still rivals. I will also do a c/3 spaceship gun, other than dart, but this time the credits will be mine. And moreover, if it is to be a dart gun, it will be smaller and run at a lower period! Unfortunately, this means p30 with Gosper glider guns, but it will still hold a record!
When scoreboards show "Rehermann vs Simkin" I will never admit, but ONLY now I used your gun to make a p360 oscillator:
