Moreover, he showed that the additive group of such a code has a strongly regular Cayley graph. Here we show that for any proper regular projective linear code C over a finite Frobenius ring with two integral nonzero homogeneous weights w1 < w2, there is a positive integer d, a divisor of the order of C, and positive integer u such that w1 = du and w2 = d(u+1).
