+Summary: PrimalityTests.SmallPrimeSppTest doesn't work...
+The SmallPrimeSppTest method in the Mono.Math.Prime.PrimalityTests class 
+doesn't work properly. It returns false even though I know the number in 
+question is a prime number. SmallPrimeSppTest is the method that is used 
+in BigInteger.isProbablePrime, so this method won't work either.
+I used the three large primes described in RFC2412 
+[http://www.faqs.org/rfcs/rfc2412.html] appendix E. When I use the 
+RabinMillerTest to test the primality of these primes, it returns true -- 
+as expected.
