UNIX for Dummies Questions & Answers

I have a file like this:

111 AA 100.00
111 AA 200.00
TOTALS 2 300.00
111 285.00
111 336.00
222 AA 250.00
222 AA 150.00
TOTALS 2 400.00
333 AA 500.00
333 AA 800.00
TOTALS 2 1300.00
333 111.00
333 222.00
333 957.00
333 466.00

I want to print out the lines when only the conditions exists that $1 appears in the file at least 4 times.

In this file, I would want to print this:

111 AA 100.00
111 AA 200.00
TOTALS 2 300.00
111
111
333 AA 500.00
333 AA 800.00
TOTALS 2 1300.00
333
333
333
333

I have searched all over for a similar example with no luck. I have played with some code, but I am not close. Any help would be appreciated.
