a..."However solving it introduces
uncalled-for 587587+193280=780367" s.b.
587587+192780=780367" i.e. another "uncalled-for"
albeit correct equation. Erred while copying from the screen.
b. I have corrected this error of mine NOW, editing the relevant post.
c. Thank you for providing ABCABC words, will select a triplet from your list as an "official" selection - choosing the least esoteric combination.
d. I've visually scanned your list, most of them look perfect, RASTER definitely cannot qualify because of the T in TARTAR. Same thing with OUTRAN. There might be other errors.
e. I believe the pattern implies existence of more than one parasitic alphametics as a valid generating equation, no matter what triplet of words is chosen.
This however does not contradict the requirements of my puzzle.
Last, but not the least - thanks for your contribution.
I intend to produce similar d4 puzzle, slightly modified.
