    <h2>Description</h2>
    <p>FeynCalc is a <a href="https://www.wolfram.com/mathematica/">Mathematica</a> package for
    symbolic evaluation of Feynman diagrams and algebraic calculations in quantum field theory and elementary particle physics.</p>

    <p>Some features of FeynCalc are:</p>
    <ul>
	  <li>Multiloop topology identification and minimization </li>
      <li>Passarino-Veltman reduction of one-loop amplitudes to standard scalar integrals </li>
      <li> Tools for frequently occuring tasks like Lorentz index contraction, color factor calculation,
      Dirac matrix manipulation and traces, etc. </li>
      <li> Tensor and Dirac algebra manipulations (including traces) in 4 or D dimensions </li>
      <li> Generation of Feynman rules from a lagrangian</li>
      <li> Tools for non-commutative algebra </li>
      <li> SU(N) algebra </li>
      <li> Tables of integrals, convolutions and Feynman rules </li>
      <li> Special convolution, Mellin transform and other integral tables </li>
      <li> Tools for calculating 2-loop propagator-type diagrams </li>
      <li> FORM and FORTRAN code generation </li>
      <li> Translation to and from FORM </li>
    </ul>
