A note on Agrawal conjecture
"... Abstract. We prove that Lenstra proposition suggesting existence of many counterexamples to Agrawal conjecture is true in a more general case. At the same time we obtain a strictly ascending chain of subgroups of the group (Zp[X]/(Cr(X))) * and state the modified conjecture that the set {X-1, X+2} ..."

Abstract. We prove that Lenstra proposition suggesting existence of many counterexamples to Agrawal conjecture is true in a more general case. At the same time we obtain a strictly ascending chain of subgroups of the group (Zp[X]/(Cr(X))) * and state the modified conjecture that the set {X-1, X+2} generate big enough subgroup of this group. 1
