That is not true, there are carmichaels numbers that are 32bit...,
but there is another priamlity testing algorithm, that is log n, and uses
something like fermat therorem, that you can do form 2,3,5 and it works
under 20 000 000.
I dont remeber how the test is done, but maybe it is that you do f
Is there any proof for this ?
