This pattern is an oscillator.
This pattern is periodic with period 31.
This pattern runs in standard life (b3s23).
The population fluctuates between 48 and 112.
This evolutionary sequence works in multiple rules, from b3s23 through to b34et5c6c8s234c6cei8.

There is a huge P31 oscillator. It is composed of 4 31 gen. delay reactions where a glider reverts a raw pattern back 31 gen.. By then it has fired 3 gen. earlier, a glider that escapes the reversion phenomenum. It looks like a "conservative reaction" but is not.

The raw matter,however, will not oscillate by itself, but needs a glider hitting it every 31 gen. So the 4 raw matters are joined by glider streams, comprising 12 gliders in all,

In my 10-19-2016 comment, I mention that some oscillators,yet unknown, have escaped the search programs, because they are TOO huge for the computer memory. Some patterns,indeed, are that big they suggest such a possibility.

I named this the FIRSTLING as it is the first of any P31 oscillators.

At the mo, there are only 4 or 5 periods for which oscillators are not known. I say 4 or 4 because P34 oscillators may be a P17 and a P2 oscillator very close together.

It is not even known whether LIFE is omniperiodical or not. Maybe the missing periods involve such huge oscillators that the search programs can not handle the memory needed.

I write the above because P31 is not a period that readily comes to mind.
