Math/Theoretical CS major: Match schools?

Some of the earlier comments regarding this OP’s need for math programs at universities or consortia may be premature in that she has not, I believe, indicated at which level of math she will begin her college studies. LACs with strong math programs are perfectly designed for a student planning to enter at the multivariable calculus/linear algebra level (and might be sufficient even for some higher-level students). Pending further information, her options would appear to be quite wide, with stand-alone LACs among them.
