Comment:
I got doctest failure with the development version
{{{
File "orthogonal_arrays.py", line 565, in
sage.combinat.designs.orthogonal_arrays.wilson_construction
Failed example:
OA = designs.orthogonal_array(6,11)
Expected nothing
Got:
doctest:1: DeprecationWarning: This function will soon be removed. Use
the designs.orthogonal_arrays.* functions instead
See http://trac.sagemath.org/17034 for details.
