Title: A high-arity counterexample to Pixton completeness in Chow.

Abstract: We disprove the Chow and rational-cohomological forms of Pixton's completeness conjecture for his original relation system. We construct a formal tautological class outside the original Pixton relation span whose image is zero in the Chow ring and in rational cohomology. The example has genus $10{}{60}$ and $3{}binom{10{}{60}}3$ markings.
