I'd vote for putting them in a single array. I'm pretty sure this will
turn out the cleanest option. You can put them together like this:

detarr=[[[det1arr]],[[det2arr]],... ]

although it would likely be better to create them in a detarr(n,3,8)
in the first place. You may find that you can carry out your entire
calculation as an operation on the array, rather than chugging through
all the elements.
