Does the Primecoin Algo have a name?

Is there a name given to algorithm used in Primecoin. I know it looks for 3 types of primes and then verifies. Is there a name given to that implementation?

prime algo, as far as I know.

What about about Riecoin? Does it have the same name?

What is the Scientific Value Behind Primecoin's Work?

Primecoin network searches for special prime number chains known as Cunningham chains and bi-twin chains. The distribution of these prime chains are not well-understood currently as even for its simplest case twin primes their infinite existence is not proven. The distribution of primes has been one of the most important discoveries in arithmetic, and the study of prime chains traces its lineage to the work of Riemann and prime number theorem, with connections to the deeper nature of the seemingly random pattern of prime distribution. Prime distribution is not just an abstract interest of mathematicians. Riemann’s study revealed connections between Riemann zeta function and prime distribution, whereas later on Riemann zeta function has been shown to be highly relevant in other scientific disciplines such as physics, thus the study of prime distribution is an important part of the foundation of modern sciences.

How is Riecoin different from Primecoin?
Primecoin uses the Fermat primality test, which has some flaws. Carmichael numbers are not prime and still pass Fermat's test for all bases, however those are relatively rare. Secondly, in general, if Fermat's test says a number is prime, it has at least a 50% probability of being prime. Primecoin uses only one Fermat test with base 2. While base 2 may provide more confidence than the general bound of 50%, still many composites will pass as primes. What's worst, is that Euler-Lagrange-Lifchitz test used for the other primes in the chain assumes the previous number in the chain is prime. So if the chain starts with a number that is not prime, then the Euler-Lagrange-Lifchitz test is not guaranteed to work, and all numbers in the chain may be composite.
Short version: Primecoin numbers are not guarranteed to be prime, they may be Fermat pseudoprimes to the base 2. There is an infinite list of Fermat pseudoprimes to the base 2 ( Riecoin uses enough Rabin-Miller tests with random bases, so the probability of a number that is not prime being accepted by the majority of the Riecoin network is negligible.</blockquote>

Since it is a Primecoin fork, I would say it’s still prime algo. Maybe you can use a different ending, such as prime-rie algo.
