I have added, mostly as local functions, some algorithms that compute the FengRaoDistance for special cases:

  • m>2c-2, using formulas, fr^(r)(m)=m+1-2genus+FengRaoNumber(r,s), fr^(1)(m)=m+1-2genus;
  • r=1, Symmetric semigroups, Arf semigroups, Semigroups with two generators
  • r=2 Arf semigroups and ordinary semigroups.
  • General r, for some symmetric semigroups
