  \section*{The library \Mex{muEC::SFA}}
  
  The \Mex{muEC::SFA} library provides functions to work with
  symmetric functions on different alphabets.  It implements the so
  called structure of \Mmath{Lambda}{\Lambda}-ring of the ring of
  polynomials.
  
  All defined bases are stored in the global variable
  \Mex{muEC::SFA::SFABases}; this is by default \Mex{[e, h, p, m, s]}.
}
