Sorry, that should be direct product, not direct sum.

This class can characterized as the direct sum of the p-adic integers
for all primes p. It is rather interesting; for one thing, it is
isomorphic to the endomorphisms of the torsion group Q/Z (where this is
understood as referring to the additive groups of these rings).

To me, it looks as if there is a generalization of the integers to a
broader
class of numbers (like F) that have p-adic representations for all
primes p.
This latter class of numbers seems to have some interesting divisibility
properties.

Since I have only a very tenuous grasp of p-adic theory, I have no idea
how
to develop this idea.
