Had a question and this looked like a good thread to post it on.
WireWorld is a four color rule.
What are some three color rules with highly flexible circuitry?
This two color rule looks intriguing, and perhaps adaptable to three colors.

If I looked at ElementaryConduits_17May2018.zip correctly, the table of enumerations looks like the following code table. No usages of D (dove) seem to be in the collection, but various mentions are in the thread. LOM and E also get mentions. There are also (non-useful?) conduits for SE (Schick engi...

Rather than ask there, I'll ask here.

Is the reason the Switch Engine got left out of the Conduit database because:
1. Known Switch Engine converters aren't useful enough

The bobsled run is known, but it also mentions simpler converters are known.

At Elementary conduit is the start of a GoL alphabet of particles. B - B-heptomino C - century / bookend D - dove E - E-heptomino G - glider H - Herschel (not J) L - LWSS M - MWSS P - pi-heptomino Q - queen bee R - R-pentomino SE - Switch engine T - T-tetromino W - wing Are there other important ite...

Oh, of course. The Unique father problem.
Are there any handy father-finding programs? I'd like to see other fathers for this pattern.

A classic time-traveler paradox involves accidentally becoming one's own parent.

Are there any Still Life objects where the only father is themselves?

What is the material at the bottom of http://conwaylife.com/wiki/R64 there for? Isn't just the Herschel and four blocks needed? It's needed to eat the first natural glider of the formed Herschel. If you open the LifeViewer, click the reset button once, and then play it, the pattern will run for eno...

May I be trusted?
