9991 is an asymmetrical 7 object siteswap where all the throws cross. The 9s should be almost twice the height of the basic pattern juggled at the same speed.
This is an excited state siteswap, starting in the state 11110111. You can transition from the basic pattern to 9991 with three 8s, and back to the basic pattern with a 4:
