John ported it to CoCoA-5.
I added it to the manual.
Found a bug: printing 0 coeff (this means it contains a summand with 0 coeff!)
/**/ R := NewZZmod(6); /**/ use R[x,y]; /**/ product([x-i | i in 1..6]); x^6 +3*x^5 +x^4 +3*x^3 -2*x^2 +0*x /**/ product([x-i | i in 1..6]) = x^6 +3*x^5 +x^4 +3*x^3 -2*x^2; -- embarrassing... false
Must add a coeff check in ring is not
