``Re: Lattices and power sets'' by CWoo on 2006-02-19 14:14:22
I found the counter-example:

Consider the power set of the reals R. Consider the Boolean subalgebra A of R generated by the following intervals

(-oo, a)
[b,c}
[d,oo)
empty set

where a,b,c,d are reals.

Then A is complete and atomless, and A is not lattice isomorphic to any power set of a set.
