For a finite integral matrix group G, compute its Bravais group which
is the integral group fixing all symmetric bilinear forms fixed by G.
IntegralGroup(G) : [Mtrx] -> [Mtrx], AlgMatElt
Return the action of the finite rational matrix group G on an
invariant lattice as an integral matrix group, thus giving an
equivalent integral group H, together with the transformation matrix
T from the standard lattice to the invariant lattice.
Thus H = T.G.T - 1.
