Eb11 chord
The E-flat dominant eleventh chord (abbreviated "Eb11 chord") is a six-note chord consisting of the notes E♭, G, B♭, D♭, F, and A♭. The chord is formed by adding an eleventh to a E-flat dominant ninth chord.
In practice, the third (G) and fifth (B♭) are often omitted from the Eb11 chord to avoid a very dissonant sound, and because it's not always possible to play all notes simultaneously.
