TITLE: Quantum 9j symbols?
QUESTION [5 upvotes]: A formula for (SU2) quantum 6j symbols exists. A formula expressing ordinary (q=1)
9j symbols in terms of 6j symbols is long known. Unfortunately, combining both (I tried it myself) got tricky - the associated graph K3,3 is nonplanar, at least one knot-type
crossing is needed and first of all, this ruins the symmetry.
Can I find the quantum analogon of the standard sum over the product of three 6j 
symbols in the literature (or can someone post it here)?

REPLY [4 votes]: to save you a trip to the library, here's the relevant paragraph from V.G. Turaev, Quantum Invariants of Knots and 3-Manifolds, page 343.
