Hooked integral or integral with hook[1] is a 10-cell still life. This still life is comprised of the normally unstable hook with a normally unstable nine attached.
It can be substitutively referred to as the integral with hook, with one pre-block of the integral sign replaced with a hook, however "hook with nine" is usually preferred for this object.
