When a system of N masses, linked together by springs, is disturbed from its static equilibrium position, then it will vibrate in a manner characterized by the N natural frequencies of the system. Should the whole system be in rotation with constant rotation speed then these natural frequencies are

An interval [a; a + d] of natural numbers veriΓΏes the property of no coprimeness if and only if every element a + 1; a + 2; : : : ; a + d -1 has a common prime divisor with extremity a or a + d. We show the set of such a and the set of such d are recursive. The computation of the ΓΏrst d leads to ris
