On codegree Tur\'an density of the 3-uniform tight cycle C₁₁

Piga, Sanhueza-Matamala, and Schacht recently established that the codegree Tur\'an density of 3-uniform tight cycles C_ is $1/3$ for ∈ \10, 13, 16\ and for all ≥ 19. In this note, we extend their proof to determine the codegree Tur\'an density of the 3-uniform tight cycle C₁₁, thereby completing the picture for tight cycles of length at least 10.
