1868130 terminates! Gets to 106 digits and then descends pretty smoothly

if you filter the blue page for 2^6*127, then the merger has to be lower than the lowest term reached by your sequence, which is 71792, and there are very few candidates. The culprit is 47560 which you can find in 2-3 clicks.

I would advise to do an update on both sequences in order to force the merge detector to delete the higher starter. This will happen on it's own over time but since the higher starter is at a low priority right now this might take a while if left alone.
