68P32.1 is an unnamed period 32 oscillator found by Matthias Merzenich on January 1, 2010. It is the second smallest period-32 oscillator known after Gourmet. It appeared in the ash of a D4_+1 soup on March 27, 2016, as part of a haul submitted to Adam P. Goucher's Catagolue.[1] It can filter a glider stream of period 32n+16 to double its period.

Synthesis

Jason Summers and Matthias Merzenich found a 37-glider synthesis of 68P32.1 in April 2010.[2] Chris Cain used the oscillator's first occurrence on Catagolue to create a 32-glider synthesis on March 27, 2016,[3] which he improved to 24 gliders on the same day.[4]
