It very much depends on what you want to do with that data. But I think you are looking for a very inefficient way to store your information.
You might, for example, use a THREE dimensional array.
INFO(x,y,[1:4]) = [5 1000 20 100];
So in the (2,7) location, we see the data has been stored as desired.
So no need to think about 6 dimensions.
Another idea, is to treat a 2-d array as essentially a database.
INFO = [2 7 5 1000 20 100];
So each row of INFO is one piece of information. You can now sort things on any of the variables.
Perhaps better yet is to use a table. Now you can name the variables. Or, you could use structs. The point is, there are so many ways you can store the data, that do not force you to create 6 dimensional arrays.
