the product of two primes, how many bases are actually witnesses? Try running PRIME?, I will be very surprised if the 35s is fast enough for you to repeat the test until a 1 appears."

Re-reading your quote, I was mistaken.
I read a bit too fast, and think you are saying until 1 [witness] appears.

Changing the word witness to non-witness made the statement un-ambiguous.
"Until 1 pseduoprime appears" also work.

999999

If the code checked this far, why the need for SPRP test ?
Any 12 digits integer, with small factor upto 999999 checked, already proved primality.
