• Lineability
• Norm attaining functionals

We show that not all infinite dimensional closed subspaces of l(infinity) satisfy that the set of their norm-attaining functionals is lineable and prove that any closed subspace of l(infinity) containing c(0) has the property that the set of their norm-attaining functionals is lineable.
