User blog:ReactorCoreZero/Omega Array Notation.

Basic Arrays: [x]=x. [x,y]=x^y. [x,y,z]= x ^(z) y, or x (z uparrows) y. 4th and after: They embed the array, with the last variable reduced by 1, into all before the last variable. If the last variable is 0, remove it. So, [2,2,2,1]=[2,2,2] in all slots=[4,4,4]>G(1). Array of operator is _, x_y is an array of y x's.

Copper Arrays: [array/a]=[array/a-1]_[array/a-1]. If a=0, remove it. [array/x,y]=[array/[array/x,y-1],y-1], so further variables act like a mini-array.
