plus Small range of R7 proven

Working on a large base like R7 is troublesome, but i still decided to give it some effort.

And after a few days i have results. The range 408034000000 up to 408034255081 is proven.

The last k just fell a few hours ago.

Code:
408034056294*7^226772-1 is prime! (191657 decimal digits, P = 3)  Time : 342.596 sec.
The results and primes can be found in results_max_range_R7.zip. The files created from srbsieve will be added in a few minutes. (Edit: added now)



I am reserving the range >408G for testing up to n=25K. [5400 k´s remaining at n=3350; quickly decreasing]

You should have reserved it first. I would have stated the following:

This is too messy to show on the pages. Sorry.

I suggest working your way upwards from k>500M (lowest untested) on the k's for this huge-conjectured base. Starting at the end and working backwards makes for too much admin work.

Alright, reserving R7 k= 500M-1G up to n=25K.
