New Period 45 Glider Gun
Matthias Merzenich has found a period-45 agar that can be stabilized with Pentadecathlons to produce the oscillator shown at left. The oscillator can be altered by moving and changing the phase of one of the bounding Pentadecathlons to create a Period 45 Glider Gun (on right). Period 45 is currently the shortest known odd period for a true-period gun.pseudo guns). The closest competitor is the pseudo-period-23 gun, in a longer and somewhat thinner bounding box (68 by 34), which miraculously interleaves two period-46 glider streams. The next smallest true odd-period gun appears to be the period-55 gun, with a much larger bounding box (291 by 250).
