16.17 ProbabilityShapes

ProbabilityShapes( pol )

returns a list of numbers, which contains most likely the isomorphism type of the galois group of pol (see GaloisType). This routine only applies the cycle structure test according to Tschebotareff's theorem. Accordingly, it is very fast, but the result is not guaranteed to be correct.
