Hey all. I'm looking at trying to generate a complete list of all maps from the integer plane to itself that have a maximal coordinate change (plus or minus) of n. Basically, I devised two wave functions that travel componentwise around the 8*n points d_inf=n from the origin, and am trying to use them to list every single equivalent map with such a metric-distance, from a point (x,y). Listed here is my current code, the problem I have on execution is that the i terms evaluate to that name as opposed to the assigned value.

I'm trying to write a loop which will display matrices of larger than 10x10, as an umbrella matrix with blocks of up to 10x10... for example an 11x14 matrix would display as a 4x4 matrix with the [1,1] element a 10x10 matrix, [1,2] a 1x10, [2,1] a 4x10 and [2,2] a 4x1. Any suggestions on how to do this or where I'd find example code? I'm an undergrad student with only an intermediate level of maple experience so I'll probably struggle with explanations with lots of jargon!
