Both are easily provable by LLR. When p=k*2^n+1, 2p+1 = k*2^(n+1)+3, but is still provable, since, by definition, we have 100%...

But the essential nature of stage 2 remains, i.e. k must have one factor between B1 & B2. That doesn't change just because you checked for the factor (i.e. did a gcd) multiple times during...

For smaller exponents, this shouldn't cost much. But how would this help...

Clearly something went wrong in the assignment itself. The closest matching prime exponent with no factors is 3885487

Considering the fact that a) TF doesn't find composite factors (outside the bit depth), b) the factors are P-1 smooth, and c) missed another factor in the range, this is almost certainly a P-1 find.

Nothing can be done on the client side. You're perhaps confusing it with improved "cost estimation" which is needed to select optimal P-1 bounds. Server logic...
