Basically a two step approach:
1) Calculate the slope that a boundary consisting of a double DRH signal must have. E.g. for 2c/5, the signal moves 10 steps to the upper left in 15 generations. If it’s part of a boundary in a 2c/5 grey ship, it would also up or down 6 steps in 15 generations. This gives (10+/-6)/10, i.e. 8/5 resp. 2/5 as the slope of the boundary, depending on whether the boundary is from with to against or the other way round.
2) The easiest way to find the actual parts is the to setup a custom WLS search setting up a field with against the grain in the lower triangle and with the grain in the upper triangle, leaving a corridor of the calculated slope, setting Xs at the ends of the corridor and simply running the search.
I propose to try this out with 2c/7 and see what the outcome looks like!
The hard part is then to combine the parts. The easy idea to use the boundaries and known with the grain technology to create an inner against the grain core cannot work, as this would give a signal traveling with the grain a speed less than c. This is already proven to be impossible.
So there must be areas where the against the grain part must reach the very boundary of the hypothetical grey ship. Those can only be found with custom wls searches that turn out to be quite cumbersome.
Unfortunately I never find the time to write the grey ship survey I wanted to write for a long time... But I’m happy to share what I have to anyone interested. Maybe you succeed where I got stuck.
