Heh heh heh, can't say I blame you for being a bit confused.

The "3rd Order" label is due to the mix products of F_a +/- 2F_b
with F_b being twice its original frequency. "Order" comes from
the constant multipliers, 1 for F_a and 2 for F_b so "1" + "2" equals
3 or the 3rd Order.

Thanks, Len. Nice to have a helpful, informative reply.
