41.0M - 41.976M to 2^61

I'll take this range.

Earlier this year I did a few exponents to 62 bits, and a few more to 61 bits,
then gave up. Someone else then took over this range, although they don't
seem to have done much. I have factored M41000021 up to 68 bits, and I am
presently working on M41000051 to 68 bits. I think I will continue doing a few
more exponents in this range up to 68 bits, and they will then be ready for
someone else to do primality tests on them.

This range is done.

24709 numbers, 396 factored.
