Sep 4, 2014 at 5:32 | comment | added | Qin Jianbin | The condition 1 is to restrain the maximum value and minimum value. | |
Sep 4, 2014 at 5:30 | comment | added | Qin Jianbin | it means number of components is n. or the cardinality is n. The absolute value difference is the abs(a-b). | |
Sep 4, 2014 at 4:25 | comment | added | Christian Stump | If you write "integer sequences", then the first condition is unnecessary. | |

Sep 4, 2014 at 1:59 | comment | added | Gerry Myerson | Does "vector of length $n$" mean square root of the sum of the squares of the components is $n$? or does it mean the number of components is $n$? | |
