  We show that there are prime knots so that the Steenrod operations of
Lipshitz and Sarkar arXiv:1204.5776 are non trivial on their Khovanov homology.
This answers a question posed by Lipshitz and Sarkar in their paper
arXiv:1709.03602. We then go on to show that there are hyperbolic and satellite
knots so that the Steenrod operations are non trivial on their Khovanov
homology.
