The 48-site and 75-site clusters used here possess all the point group symmetries of the (infinite) kagome lattice. Although they do not accommodate the VBC 36-site cell, they still capture correctly the local physics around impurities. The largest Hilbert spaces are obtained for a single impurity in 75 sites (4 194 304 symmetrized states) and for two spinons and two impurities in 48 sites (8 511 488 states)
