Gets the solutions in the interval [first..first+len-1] and spans the complete designs. Each design is returned as a list of blocks. See span_design for remarks on how the blocks of the design are ordered.
Spans the design given by a list of base blocks in bb under the group in grp. Returns a list of blocks of the design. The blocks come in the order of orbits of the base-block vector bb. Thus, they are not lexicographically ordered. There is no relabelling of points so the resulting incidence matrices still have the original group as group of automorphisms.
Converts a solution vector to a list of orbit indices.
