The owner of the link can read it.

A member of the link's group other than its owner can read and write it.

Additionally the SGID bit is set, which means different things for different resource types.

Others

Any other user on the system cannot access it at all.

Additionally the sticky bit is set, which really only means something on directories, these days.
