<h3>
Description:
</h3>
This function computes the lengths of the blocks of the Galois group
of the order
using subfields. Transitive groups with other block systems
are excluded from the list of possible Galois groups. Is the
second parameter used, this function computes the Galois groups
of the subfields and excludes transitive groups with other
Galois groups of the subfields from the list of possible Galois
groups.
