One new solution:

(6,2,5) 235352+198157=241276+165166+145299+123186+27462
by Serge Vannieuwenborgh and DoctorNow

235352^6+198157^6=241276^6+165166^6+145299^6+123186^6+27462^6

One more new primitive solution:

168125^6+145417^6=99907^6+13914^6+53508^6+124712^6+173481^6
(GLaDOS and Laurent Evrard)

ps. We can finish this new Boinc project in about one year. Currently we completed 3-4 percentage of the whole search space in about 10 days.

I think that it will be finished in around 3 months.

is there any reason why both checks are done at the same time?

would it not make more sense to do each combination once, and come back for the double check later?

by doing single checks you can get through the search-space a lot quicker (nearly 2x). you can schedule the double check for 'positive hits' immediately, and the 'misses' can be re-checked towards the end.

yes/no?

This is a BOINC feature. The server generates two WUs and validates the results of two different hosts against each other. Most BOINC projects assure the quality of their results that way. It would be extra work to generate the "check WUs" at a later time.

Furthermore, in your example checks would be done, too, so you will have to crunch each WU twice anyway. And one more thing: If you already crunched all WUs once, the motivation to crunch them all again would be pretty low.
