There are generating functions to discover instances of certain values such as k=2,5,65 which do not appear for small bases.

This is down to the work of Chris Caldwell and his last year students.

for example k=2 for b=19590496078830101320305728

Is this the lowest base where k=2 is the Sierpinski number?
