We obtain information on torsion in Khovanov cohomology by performing calculations directly over [Formula: see text] for [Formula: see text] prime and [Formula: see text]. In particular, we get that the torus knots [Formula: see text] and [Formula: see text] contain torsion of order [Formula: see text] and [Formula: see text] in their Khovanov cohomology.
