k=1963
I take k=1963, at least to n=500k.
Already completed up to n=120k. (My first small contribution here) Primes for n= 7, 11, 15, 55, 91, 95, 127, 131, 135, 847, 2379, 2471, 8831, 11527, 11967, 17439, 26619, 26899, 28519, 36635, 36695, 81975 All confirmed from Rieselprime, except n=81975, which is new (previous search up to n=50k).

 11069  11411  20639  21869  10453199  10813783 However I will keep on testing the following k:  25935 Templus / I. Goudt

k=19920911 is a low weight k so i was rather lucky
k=1145699 only has about 700 tests from 1 until 1mil so that is an especially low weight k what i am doing with k=1145699 is easier that a 6th drive file i think Last fiddled with by henryzz on 20081102 at 07:25

k=1963 tested up to 220k and moving on.
One new small one, n=169071. k=7605 tested from 439k to 452k and moving on. Nothing found.
