 OFFSET 1,1 COMMENTS Primes in A135641. Primes whose structure of digits represent a convex function or a convex object. In the graphic representation the points are connected by imaginary line segments (or line curves) from left to right. See A246033 for a different notion of "convex prime". - N. J. A.
