There already are several questions on this site about this exact question: math.stackexchange.com/questions/1522720/… math.stackexchange.com/questions/1783226/… math.stackexchange.com/questions/1951669/… math.stackexchange.com/questions/1958465/… (And maybe you can find more.) — Martin Sleziak 4 mins ago

@MartinSleziak I have noticed quite curious fact that there were some posts which contained both type of links, like here. I have stumbled upon a few such posts when editing.

This seems to be a duplicate of $A \in M_3(\mathbb Z)$ be such that $\det(A)=1$ ; then what is the maximum possible number of entries of $A$ that are even? (General advice: search before posting.) — Martin Sleziak 37 secs ago
1573584: $A \in M_3(\mathbb Z)$ be such that $\det(A)=1$ ; then what is the maximum possible number of entries of $A$ that are even?
2042821: How many entries in 3x3 matrix with integer entries and determinant equal to 1 can be even?
The newer question was for some time on the HNQ list, so it already has two answer (the older one has only one) and about the same number of views.
I have edited the title to be mor clear than the original title "How to enumerate this linear algebra problem?" But I still did not use MathJax (so that it stays in the HNQ.)
So I guess that a reasonable thing to do with those two questions is either close in the direction older $\to$ newere or merge, right?
I am not sure whether this is a factor, but the older question would be a reasonable candidate for missing context closure.
The question is a duplicate of the linked one from 5 days ago (search the site - at least the recent ones). I used that as a duplicate target, because it has an answer. However, I upvoted your question. At least you thought about the matter (unlike the other asker). You also found the correct answer! — Jyrki Lahtonen ♦ Dec 18 '15 at 6:05
