Period-odd G4 receiver (click above to open LifeViewer)
P-odd G4 receiver or Period-odd G4 receiver or Odd-period G4 receiver or P(2n+1) G4 receiver is a G4 receiver that only works for odd periods because the blinker (which is a catalyst for the R-junk at the back) changes phase every time a pair of gliders is sent to the receiver.
