Slight correction : it used to be every four hours (about a year ago), but it is now every eight hours.hotdogPi wrote: September 7th, 2025, 2:25 pmFour hours.

No. A hassler needs to have a supporting mechanism that remains stable/periodic without the presence of the hassled object(s).I6_I6 wrote: September 9th, 2025, 2:37 pm Does the spark coil technically count as a p2 pi heptomino hassler?

Many. See oscillator and table of oscillators by period on the Wiki. For example, all periods whose smallest known oscillator is a rectifier loop must have minpop above 100, since two rectifiers together without gliders is already over 100 cells. The highest population SKOP (Smallest Known Oscillator for each Period) is p67 with 228 cells. I believe it's the only remaining SKOP that still uses a snark loop.mmmmmmmmm wrote: September 12th, 2025, 10:44 pm Apart from p41, what periods are there where the smallest oscillator of that period hasa minpop above 100?
If you mean the connected way, use two pre-blocks.
