We consider an isotropical inertial reference frame (\"stationary\") and in it a uniformly rotating circular platform of radius R. The velocity of light c relative to the rim of the platform is calculated and found to have values necessarily different from c. This c remains the same if R is increased but the peripheral velocity is kept constant. Since by so doing any small piece of the circumference can be considered better and better at rest in a (\"moving\") inertial system, the velocity of light relative to this system can be deduced. Noninvariant values are obtained and shown to coincide with the predictions of our recently published \"inertial transformations\".
