We study quadrics and quadratic forms in a projective space over a local ring R = 2R whose maximal ideal is principal and nilpotent. The problem of enumeration of classes of projectively equivalent quadrics is completed for |R \* : R \* 2 | = 2; when |R \* : R \* 2 | = 4, the problem is solved toget
