Nodes of a general plane projection of a projective curve

Let Xsubset ofPn, ngreater-or-equal, slanted6, be an irreducible non-degenerate curve and f:X→P2 its general plane projection. Set Zcolon, equalsSing(f(X))-45 degree rulef (Sing(X)) and zcolon, equalscard(Z). If nless-than-or-equals, slant7 assume zgreater-or-equal, slanted25. Here we prove that the monodromy group of the generic apparent singular set Z is either the alternating group on z elements or the full symmetric group on z elements.
