The sums of components of the ground states of the O(1) loop model on acylinder or of the XXZ quantum spin chain at Delta=-1/2 (of size L) areexpressed in terms of combinatorial numbers. The methods include theintroduction of spectral parameters and the use of integrability, a mappingfrom size L to L+1, and knot-theoretic skein relations.Comment: final version to be publishe
