Query: The elliptic hypergeometric function and $6j$-symbols for
  SL(2,$\mathbb{C}$) group   We show that the complex hypergeometric function describing $6j$-symbols for
$SL(2,\mathbb{C})$ group is a special degeneration of the $V$-function -- an
elliptic analogue of the Euler-Gauss $_2F_1$ hypergeometric function. For this
function we derive mixed difference-recurrence relations as limiting forms of
the elliptic hypergeometric equation and some symmetry transformations. At the
intermediate steps there emerge the function describing $6j$-symbols for the
Faddeev modular double and the corresponding difference equations and symmetry
transformations.
