However, when 720^20 is evaluated to 1401683395356260729391818575873415577600000000000000000000 first, and then the Jacobi program is called, I also get 52175039830928864354013492999359544 in about 1.4 sec. It turns out, that it fails for some kind of algebraic terms like 'a^b' or 'a*b', but not all of them (e.g. '3*11' seems to work well). To make it save, an 'EVAL' should be added to the Jacobi program: Code: %%HP: T(3)A(R)F(.);
