Comment (by vdelecroix):
Though, we have currently the following behavior that I do not quite
understand
{{{
sage: Ktemp.<atemp> = NumberField(x^2 + 2*3*7*11)
sage: m = atemp.matrix()
sage: m.set_immutable()
sage: K.<a> = NumberField(atemp.minpoly(), embedding=m)
sage: a*m
[-462 0]
[ 0 -462]
sage: sage: a*m == m**2
True
}}}
