Useful calc links:
If are interested in algorithms for finding very large primes:Some of the methods used by the Amdahl 6 to discover (what was at the time of discovery, the largest known nonMersenne prime): (391581*2^2161931) are contained in the calc script lucas.cal. This calc script is available as part of the calc distribution.The tutorial on how to find a new largest known prime goes into detail about the above mentioned Amdahl 6 lucas.cal method.
If are interested the product of curious primes:See the curious calc web page.
