The pre-pulsar is a common predecessor of the pulsar. It duplicates itself after 15 generations, although it fails to be a true replicator because of the way that the two copies then interact.

A pair of tubs can be placed to eat half of the pre-pulsar as it replicates; this gives the period 30 oscillator Eureka, where the pre-pulsar's replication becomes a movement back and forth. The replication of the pre-pulsar can also be made to occur in just 14 generations as half of it is eaten; this allows the construction of period 28 and period 29 oscillators, and is in fact the only known method for creating a period 29 oscillator. The pre-pulsar is also a vital component of the only known method for constructing period 47 oscillators, and a similar reaction is the key component in the first discovered period 22 oscillator.

A common four-generation predecessor of the pre-pulsar that consists of two T-tetrominoes
