Which Division IA schools do not have university in their names?

I know of 5.. Boston College, Georgia Tech, Army, Navy, Air Force

You are forgetting MIT (Massachusetts Institute of Technology).

MIT is an Ivy League school and they only compete in Division 1A Basketball which includes 1AA (which has quite a few schools without University in their official school name) as well.

MIT is NOT an Ivy League school - it is a Division III school
