The old Nash tool as given here in this thread was specifically created for k*2^n1 and will yield: Code:
nash 93 > 93 3116 3123 The new (universal) Nash tool (originally created upon your request) and given in another thread yields the correct answer: Code:
nash 93 10 > 93 5030 5045 BTW.: Note the sign change between the two versions: For the new one enter negative k for the Riesel side, e.g. k*b^n+1 for k*^b^n1. Regarding your second question: mnash is restricted to base 2. But one could easily write a little Python or Perl script which does the looping over k and calls the new Nash tool...

I prepared a new version of mnash which is now also capable for bases other than b=2.
For convenience the attached ZIP file also contains the latest single k universal base nash.exe. A positive k means k*b^n+1, negative k means k*b^n1 (e.g. entering as k*b^n+1) Usage examples are given below: Nash weights for sequences k*3^n1 (for even k=1020): Code:
mnash 20 10 2 3 (= kmin kmax kstep base) 20 3 2960 2960 18 3 2686 2667 16 3 1430 1435 14 3 1524 1523 12 3 2359 2369 10 3 4054 4038 and for k*7^n+1: Code:
mnash 10 20 2 7 10 7 4000 3979 12 7 2407 2411 14 7 0 0 16 7 3211 3210 18 7 2392 2387 20 7 0 0 Code:

I did some minor improvements to the "mnash" tool:
(1) The earlier version was restricted to k<2^31, the new one can handle k of arbitrary size. (2) The values "kmin" and "kmax" now have the meaning of start and stop values and you're no longer restricted to (numerically) increasing order. (3) The sign of the step size doesn't matter. It will be adjusted properly. So a step size of 2 may be entered as "2" oder "2". (4) If only kmin and kmax are given, a step size of 2 is assumed. And base=2, of course. To give an example: Code:
mnash 2 10 2 13 2 13 3721 3713 4 13 0 0 6 13 1416 1414 8 13 963 965 10 13 0 0 Code:
mnash 123456789012345678901234567890 123456789012345678901234567880 2 7 123456789012345678901234567890 7 3543 3571 123456789012345678901234567888 7 1370 1345 123456789012345678901234567886 7 0 0 123456789012345678901234567884 7 2876 2886 123456789012345678901234567882 7 2171 2148 123456789012345678901234567880 7 0 0

Can you make modification of this tool adding just one number
1 100 2 2 10 Last number means: print only K that have weight 10 or less.

Multi5 is still way faster then mnash.
So also can you just change behavior of last number 32000000025 KMIN 32001000000 KMAX 30 KSTEP 600 minimum weight for printing Since if we use this tool we look at very small weight of number do that last number print only K less then not above then ( as it now) With that output will be drastically smaller . Thanks

I typed "nash 127"
It prints "127 325 332" Thus the weight of 127*2^n+1 is 325 and the weight of 127*2^n1 is 332?
