Neferefre's prenomen was in all probability also given on the Turin canon (third column, 21st row), which dates to the same period as the Saqqara tablet, but it has since been lost in a large lacuna affecting the document. Nonetheless, the part of the reign length attributed to Neferefre by the canon is still legible, with a single stroke sign indicating one year of reign to which a decade could in principle be added, as the corresponding sign would be effectively lost in the lacuna of the document.
