assitance with sed (repeating patterns)

hi,
I need to write a command to look into a text file, find lines that contain patterns of three or more characters that repeat once, and put perenthesizes around them. so for example, the line "123test123" would be changed to "(123)test(123)" and "abcdeabcde" to "(abcde)(abcde)".
any hint is appreciated.
