My primary object is to provide complete listings of the factorizations up to the highest completely factorized exponent for bases 2 to 999.
Other listings (in print and on the Net) omit one or more of the following:
My secondary object is to try to help complete the factorizations for exponents up to 50. My contribution to this is minor: of 28,076 non-trivial factors in my database, I claim to have discovered only 1,106 (3.94%) of them.
