      I have formulated another composite test variant:

      Non-square N>5, with gcd(30,N)==1, is prime if and only if for any integer x:
      gcd(x^3-x,N)==1 and
      jacobiSymbol(D,N)==-1 and
      x^(N-1)==1 (mod N) (Fermat) and
      (L^2-1)^(N+1)==-D (mod N, L^2-x*L+1)
      where D=x^2-4.

      I have a long list of such conjectures, all of which will be tested to some high level, once my other projects are cleared,
