Request for math-history help from readers fluent in Russian: strong-probable-prime tests (see https://en.wikipedia.org/wiki/Probable_prime) are sometimes credited to Artjuhov (http://matwbn.icm.edu.pl/ksiazki/aa/aa12/aa12125.pdf) but the closest I've found there (middle of page 363) needs Jacobi symbols. Am I missing something?
