Abstract:

Algorithms are described to obtain explicit primality criteria for integers of the form $h \cdot {2^k} \pm 1$ (in particular with h divisible by 3) that generalize classical tests for ${2^k} \pm 1$ in a well-defined finite sense. Numerical evidence (including all cases with $h < {10^5}$) seems to indicate that these finite generalizations exist for every h, unless $h = {4^m} - 1$ for some m, in which case it is proved they cannot exist.
