McNugget Numbers

In the 1980s, while eating McDonald's with his son, mathematician Henri Picciotto reasoned McNugget Numbers.

At McDonalds’ Restaurants at the time, Chicken McNugget meals were available in sizes of 6 McNuggets, 9 McNuggets, or 20 McNuggets.

A number is a McNugget number if it can be the sum of the number of McNuggets purchased in an order before eating any of them.

Some Examples:

	20 + 6 == 26
	9 + 9 + 9 + 9 + 9 == 45
	20 + 9 + 6 == 35
	...etc

###Task 1

Determine all numbers that are not McNugget numbers using 1980s order sizes - 6, 9 and 20.

###McNugget 2015 Redux
