September 4: 400spartans constructs a 278-cell unconstructible still life, smaller in population and bounding box than the previous minimum 306-cell version.September 6: Keith Amling completes a period-6 c/3 orthogonal ship containing a simple wick.September 9: Hartmut Holzwart constructs a new type of c/2 orthogonal agar ship.September 18: Mitchell Riley discovers 86P107, the first engine-based period-107 oscillator, and the smallest known oscillator of that period.September 23: Evin discovers compact, stable glider pulse dividers with new period multipliers of 5, 11, 12, and 4+6n.September 24: Carson Cheng discovers a period-76 shuttle for a pair of pi-heptominoes which, at 52 cells, is the smallest known oscillator of this period.September 15-28: Collaborative progress on enormously long-lived diehards continues on the "engineered diehards" thread, passing the threshold on September 28 of 11^^^3 = 11 ^^ (11 ^^ 11) ticks (where ^^ is the operator for tetration, i.e., iterated exponentiation).October 5: Based on a partial result by Mitchell Riley, iNoMed completes a p42 glider gun fitting in a 32×23 bounding box, making it currently the seventh smallest true-period glider gun. Goucher and Evin, with a similar sized bounding box (116×86).
