| Feb 16, 2014 at 5:18 | comment | added | Brendan McKay | This question is also interesting if only subsets of a given fixed size are considered, rather than all subsets. | |
| Feb 16, 2014 at 1:29 | comment | added | vzn | bears some resemblance to the subset sum problem from TCS have you heard of it? | |
| Feb 16, 2014 at 0:43 | comment | added | user9072 | @vzn I assume the idea was only to stress that it is not modulo 2. | |
| Feb 15, 2014 at 16:13 | comment | added | vzn | why addition over $\mathbb{R}$ and not $\mathbb{N}$ if all the elements are also in $\mathbb{N}$? | |

| Feb 15, 2014 at 13:24 | comment | added | Simd | @AlexDegtyarev Ah well that is not something I can judge for someone else :) If it helps motivate it, the equivalent question for integers rather than vectors has exercised such luminaries as Erdos and others. See e.g. ams.org/journals/proc/1996-124-12/S0002-9939-96-03653-2/… | |
| Feb 15, 2014 at 13:22 | comment | added | Alex Degtyarev | To me, the distinction is that a puzzle is not worth investing too much effort :) | |
| Feb 15, 2014 at 13:18 | comment | added | Simd | @AlexDegtyarev Really it's a puzzle at this point although maybe I don't fully understand the distinction. What I mean is that there is no greater goal than my interest in how one would solve the problem. I did however try smaller dimensions and my guess is that the optimal answer is no more than $20$. | |
| Feb 15, 2014 at 12:32 | comment | added | Alex Degtyarev | Is this a puzzle or a problem? If it's a problem, did you try smaller dimensions? That might help to guess the pattern. | |
