As far as I understand the assert function, the tests #13, 15, 17 and 18 actually appear to be wrong (!) since accordind to Matlab isprime function theirs inputs are not prime numbers (resp 99194853094755497, 1066340417491710595814572169, 19134702400093278081449423917, and 10888869450418352160768000001). Could you please double check these tests ? Thank you.
@Nicolas they're all primes, but they all exceed flintmax, and I think isprime() does not handle such numbers reliably (arguably something its documentation should mention).
Thank you Christian for explanation :-)
