n > 2, output the result of [1×2×n, 3×4×n, 5×6×n, ...]. The final element will be n×n if n is odd, and (n-1)×n×n if even. Essentially, break the range to n into pieces of 2, get their products and multiply each by n 
In mathematics, an identity element, or neutral element, is a special type of element of a set with respect to a binary operation on that set, which leaves any element of the set unchanged when combined with it. This concept is used in algebraic structures such as groups and rings. The term identity element is often shortened to identity (as in the case of additive identity and multiplicative identity), when there is no possibility of confusion, but the identity implicitly depends on the binary operation it is associated with.

Piet, 15x15(225) 13x15(195) codels
I think Piet program size is counted by codels. If someone wants to know the size in bytes anyway, I could shrink it down to 495 bytes(15x15 codels) and 476 bytes(13x15 codels) using PNGGauntlet.
Codel size 10 for better visibility.
