12 Days of Christmas (Posted on 2018-11-03)

Over the course of the 12 days of Christmas, according to the song, how many of each type of present did the singer's true love send? ... such as 12 partridges and 22 turtle doves.

Please give the formula and the 12 numbers, so we can see the most and least abundant gifts.
