I can't reproduce A140532 beyond the first two terms if the author's
using "pandigital" for "distinct digits".
I think it's even more restricted, namely "distinct digits with no 0".

And even with that, I can't reproduce the last nonzero term, which I
find as 23082, not 55440:

h: [4, 20, 83, 395, 1610, 5045, 12850, 55440]
m: [4, 20, 83, 395, 1610, 5045, 12850, 23082, 0]

Might be worth checking yourself; my insomniac-mode programming is
notoriously unreliable.
