We construct Euclidean lattices whose sets of minimal vectors support some large equiangular families of lines, using notably reduction modulo~$2$ of lattices. %as considered in {Ma1} and {Ma2}. We also consider some related problems, and answer a question raised by Greaves ([G], Subsection~1.3.2).
