### On a certain type of primitive representations of rational integers as sum of squares

Arenas, A. (Àngela), 1955-

It is well known that a positive integer not of the form 4a (8m+7) can be expressed as a sum of there integer squares . Dirichlet (cf . [1]) proved that a positive integer admits a primitive representation as a sum of there squares if and only if it is not of the form 8m+7 or 4m .
