Program PARI/GP

• finding roots of a polynomial with rational coefficients (over C or Q_p),
• calculating the Galois group of (the minimal splitting field of) an irreducible polynomial,
• calculations on elliptic curves (adding points, finding the torsion subgroup etc.),
• and many others

To run PARI/GP, use the command gp (you should be logged in at mccme.ru). You will see a command prompt beginning with a question mark; you can issue any PARI/GP command in the command line. E.g., if you input a question mark (one more), you will see a brief list of topics for which you can get help. If you input two question marks, you will see the file /usr/local/lib/pari/doc/users.dvi, which is a very detailed (more than 200 pages) manual; note that it is impossible to read it from the console: you need some window manager to do it.
