The motivation for the definition of wrappable class comes from results such as the Boone-Higman theorem, which states that a countable group "G" has soluble word problem if and only if it can be embedded in a simple group "S" that can be embedded in a finitely presented group "F". Houcine has shown that the group "F" can be constructed so that it too has soluble word problem. This together with the fact that taking the direct product of two groups preserves solubility of the word problem shows that:
