Math Puzzle: What does this list of numbers and letters represent?

This is a list of values I had generated, while preparing some... "mathematically interesting"... material for my upcoming birthday party. (I was born on March 10, 1977.)

The first person to figure out what it is gets a "prize" of some sort.
