✦ Synopsis
Partitioner algebras are deÿned by Baumgartner and Weese (Trans. Amer. Math. Soc. 274 (2) (1982) 619) as a natural tool for studying the properties of maximal almost disjoint families of subsets of !. We prove from PFA + and ♦(S 2 0 ) that there exists a partitioner algebra which contains a subalgebra which is not representable as a partitioner algebra.
