  • jamon34p13.1

    The smallest known period 39 oscillator as of April 2009, though it is usually considered trivial because there is no individual cell that oscillates at the full period.

  • jaggedlines

    Jagged lines of gliders, formed by a drifting collision of two LWSS streams, crash to form an approximately vertical jagged line of pairs of blocks. I don't know if the line stays within a bounded distance of the center line, or extends infinitely far to the left, or to the right, or both. https://www.conwaylife.com/wiki/Jagged_lines
