ntzfind can search oscillators?

My bad thanks, corrected.

Here is a signal rulespace with cardinality 78 and oscillators of period 4, 6, 8, 13, and above.
It is between B2ci3a/S02i3i6i and B2ce3-iny4-kt5-i678/S01c2-a3-eq45678.
...

Here is a signal splitter which works in the same rulespace as the reflector, along with a 0 degree reflector.

Can anyone corderize this?

These kind of posts barely add anything new ontopic. There is a dedicated topic tor that out there, in an other subforum.
Actually, the first successful corderization attempt is on this side, just scroll up or grep the rulestring https://conwaylife.com/forums/viewtopic.php?f=11&t=5933 ...

Never mind, it was so easy, made in a snap.

There's a puffrake to be corderized every day:
