| Dec 30, 2014 at 17:39 | comment | added | Winther | Hehe. No problem, it happens. Anyway, this still stands as a very good example of how to write a good question: Proper context with references, some claims/calculations and then the question. If only more people here put so much effort into writing questions:) | |

| Dec 30, 2014 at 17:07 | comment | added | Jean-Claude Arbaut | @Winther How could I possibly miss this? I saw the first equation, but completely failed to see the common $p$ factor, hence the simplification when taking $\mod p$. Thank you! Make this an answer, you deserve the bounty, and I deserve a good kick in the sas! | |
| Dec 30, 2014 at 16:54 | comment | added | Winther | Maybe I'm misunderstaning here, but getting the seed seems simple. We have $mx = (qr)ix + (pr)iy + (pq)iz $ so $mx \equiv ix(qr)\mod p $. This is a simple congurence to solve and it gives us the seed $ix$ (and similar for $iy$, $iz$). In your case we get the equation $918999161\cdot ix \equiv 2754208631 \equiv 2052 \mod 30269$ which has the solution $ix=1$. | |
