Square repeat numbers

I'm at college in the UK and studying A-Level Maths and Further Maths. Our
teacher has given us a problem, just for fun, not actual homework, which I'm
interested in solving. Please let me make it clear that I want no answers to
this problem; just some pointers in the right direction please, as answers
would ruin the fun.

The question is: Are there any square repeat numbers? (A repeat number being
any number, which is made up of a repetitive pattern of other numbers, eg.,
592592 or 365345365345 or 999 or 100100 or 2222 etc........)

I've written a computer program to try to solve this with brute force
checking of every number, but I wasn't sure that this was working correctly
and it gave no results up to the limit of language's highest-precision
numeric data type.

Thanks for your help,

Richard Hayden.
