Karel's p177, also known by its systematic name 104P177, is a period 177 oscillator discovered by Karel Suhajda in June 2007.[1] In terms of its minimum population of 104 cells, it is the smallest known period 177 oscillator. It can serve as a 90° or 180° degree reflector, and with the correct phasing, a glider can pass through it unharmed. On March 21, 2009 Jason Summers found a 24-glider synthesis of this oscillator.
