Descriptive Data: (report abuse)
A Probable Primality checker for numbers of the form Phi(2^s*3^t,b), the Generalised Eisenstein Fermats. This suite of programs is essentially the backbone of the Prime Internet Eisenstein Search (PIES). Numbers of the form Phi(2^s*3,b) are exceptionally quick (compared to other programs capable of PRPing such forms) due to the use of a bizarre and novel transform algorithm. Written entirely in C, this can in theory be ported to almost any architecture - inquire within...
