Genus formula conjecture for lens space knots in \Sigma2,3,72,3,7

About 8 years old · traced to

Let Kp′,kK_{p',k} be any knot whose parameter (p′,k)(p',k) occurs in the displayed table for lens space surgeries in Σ(2,3,7)\Sigma(2,3,7), and let g′g' be the table's value in its g′g' column. Genus formula conjecture. Its genus satisfies

g(Kp′,k)=g′+p′+12.g(K_{p',k})=\frac{g'+p'+1}{2}.

The table supplies examples of lens space knots in Σ(2,3,7)\Sigma(2,3,7), and the conjecture predicts their genera from the tabulated data; the source does not state a resolution.
