Hmm, maybe that's just a typo, but that would be an 81/64 and not an
81/80.

Pythagorean comma B# is HIGHER... then how can it be a "pure" ratio,
since the just third a SYNTONIC comma away from the Pythagorean third
would have to be SMALLER... by 22 cents...

Fb, or 8192/6561 is the near 5/4, or Pythagorean schismatic third...
so if you were to spell a C major triad C Fb G in a Pythagorean
tuning, you'd have a very near 4:5:6 (C E G), which I think is what
your getting at - though I'm not entirely sure!
