The association of histone H₁ with a nucleosome indicates 

Nucleosomes constitute a repeating unit of a structure in the nucleus called chromatin. H₁ histone, also known as linker histone or H₁ linker histone, is a structural protein that plays a crucial role in the organization of DNA within the nucleus of eukaryotic cells. It is involved in the formation and stabilization of higher-order chromatin structures by binding to the linker DNA that connects adjacent nucleosomes.
