Comment (by jpflori):
I'd say David used the term tree because a PCPT objecgt only contains one
layer of references, i.e. a pseudo-conway poly and refs to the PCPTs for
n/q where q is a prime divisor of n.
Some minor remarks:
* I think we should add a warning that PCPTs are only weakrefed. I saw
that you correctly took care of that in #8335, thanks for that.
* At some point the new doc says "The following demonstrate coercions",
shouldn't it be "demonstrates"? (please pardon me if I'm wrong, I'm
english expert).
* The doc changes corresponding to the fix mentionned in
http://trac.sagemath.org/ticket/8335#comment:59 are missing; it should not
read:
{{{
If False, then `n` is prime and
no references are stored (since there is no compatibility
condition).
}}}
but:
{{{
If ``False``, then `n == 1` and no references are stored
(since there is no compatiblity condition).
}}}
