So far there is no evidence of either compositeness or supersymmetry. Deviations from the SM couplings is proportional to the degree of compositeness of the particles. Furthermore, 24 is a Fermat witness for the compositeness of 221. These schemes also anticipate "partial compositeness". The simplest probabilistic primality test is the Fermat primality test (actually a compositeness test). Therefore, the latter might more accurately be called "compositeness tests" instead of primality tests.
