These schemes are similar to Lebedev's schemes, but are determined to higher numerical precision. I have also heard that Delley's grids do not suffer from the problem of negative weights, which affects some Lebedev grids.
I have asked Delley by email whether he would be willing to contribute his grids.
Delley published high order integration schemes on the unit sphere in J. Comput. Chem. 17, 1152 (1996).
