User:Entity Valkyrie 2/R-junk
The R-junk is an object left by the R-pentomino after it turns into a B. It can be turned into a hive and a pair of blinkers which can be used for the P-odd G4 receiver. Alone, it stabilizes at gen 189 into 2 traffic lights, a honey farm, a block and a glider. It can be eaten cleanly with a loaf, as in RF28B.
