Abstract: In this note we prove that there exists a Caratheodory vector lattice $V$ such that $V\cong V^3$ and $V\ncong V^2$. This yields that $V$ is a solution of the Schroder-Bernstein problem for Caratheodory vector lattices. We also show that no Caratheodory Banach lattice is a solution of the Schroder-Bernstein problem.

Keywords: vecrot lattice, Boolean algebra, internal direct factor
