There is no defacto set, because the Pyy numbers only exist for LCAD purposes,
and the numbers are not allocated until somebody goes to the trouble of
authoring the part - so the "Master list" is, in effect, the current PARTS.LST
file in your LDraw directory. Even Pyy numbers which appear on the Parts
Tracker may change prior to officialisation of the LDraw DAT file, due to lack
of central control. I thought of including a list of the files with Pyy names
at the foot of the posting, but it's 297 entries long.

The Xnnn numbers on peeron.com appear (?) to have been assigned independently
from the Xnnn numbers used by parts authors. My understanding of the latter is
that authors submit parts with Xnnnn numbers if they are personally unaware of
the part number. During the (now defunct) vote preparation process some TLC
numbers often came to light, so the DAT files would be renamed. If no TLC part
number could be discovered, then the Xnnnn part would be released as nnnn
(where nnnn <1000). So any Xnnnn number you find on the Parts Tracker will a)
not necessarily tie up with peeron.com, and b) only be a temporary number never
to be released as a final dat file (it will either be renamed to the true part
number or released as nnnn.DAT). Indeed all LDraw part numbers <1000 are
theoretically temporary, as one day we may discover their true identity. They
have slightly more permanence than a number in a list in that the nnnn.dat file
will always exist (for backward compatibility reasons), even if it becomes a
"~Moved to" redirection to the real file.

Agreed, but how can you be sure you are not just creating another _definitive_
list, that may be as perfect as you can make it today, but will soon grow out
of date as new information / parts come to light? I am sure all the other lists
set out with the aim of being as complete and accurate as possible.
