I thought the triangle wave had even harmonics in it, but found out it
actually has odd harmonics but they decrease with the square of the order
instead of just a simple 1/N.

It is the sawtooth (equal slopes at rise and decay) that is made up of
even harmonics.

(I cannot speak with any authority in the triangle wave)

Oops! Got the two swapped round!

Square = odds, Triangle = evens, Sawtooth = raucous!
