@Monique why don't you try to answer the numbered points in this answer. we will be happy to provide more hints then.

@Monique you really should exhibit some work yourself, that would give us some reason to give more hints, if needed

comment Finding a Closed Form of a Two Dimensional Recurrence
Is the intent for $a_{n,m}$ with $n \ge m$? Otherwise it seems $a_{2,1} = -1/2$? In other words, if you don't want to define it for $n > m$, the first initial condition only gives $a_{1,1}$, no?

comment maximum value of the determinant
Interesting. They certainly should be linearly independent, otherwise the determinant is 0. I assume if you have orthogonal ones, it maximizes the determinant, but not sure why that happend geometrically. Can we related $det(A)$ to the angle between the columns, in the $2 \times 2$ or $3 \times 3$ case? The only thing is can think about is that determinant is the product of eigenvalues...

@QuanticProgramming added a graph and some notes to make some intuition.
