You are designing system-level tests for a blogging platform with multiple configuration options. You have extracted the following features, with the following value classes for each:

Cookie Options	Enable Subscription to Posts	Advertising	Post Editor	Content Host	Comments
Allow	Enable	Targeted	Rich Text	AWS	Closed
Restrict	Disable	Non-Targeted	HTML	Azure	Anyone can Comment
Block		None	Markdown	Self-Hosted	Registration Required
		Text-Only		Google Cloud

The full set of possible test specifications contains 864 options.

Create a covering array of specifications that covers all pairwise value combinations in fewer test specifications. Try to create the smallest array you can.

(hint: start with two variables with the most values and add additional variables one at a time)
