This post carries out the blue/green color trials to confirm or deny the blue-to-yellow cluster merge in the Easter Monster.
(S3m, SE3m, r7np48).
The removal leads to a contradiction that dooms blue candidates of a possible yellow to blue merge.
Both the entire trial trace and a diagram of the inference path from removal to contradiction is below. It takes a lot of patience to follow it in either form, but it took no special insight to generate the trial trace, and then the diagram from the trace.
This time, the red ANL forces NW8, and the green ANL forces both SW4 and SE4 in r7.
The trials end with blue-to-yellow implying not blue and not green. A hung jury and the Easter Monster walks. But not far.
Already 7-patterns are trapped down to two, one blue and one green. The solution takes no more than what we have already done with EM, so go for it. And be sure to tune in next week for the final court room scene.
