matching repeated character

looking for a bit of help with sed.

I have a file that looks a bit like this:
Code:
sdfghhjk
asdfdfghgj
asdfhgghj
werdfvtfh
edftbgh
1211211221
sdffgfm
dfghnhjm
dfvfsgbgh
adsfv bdhgn
1111111dffg
dfv1122
dsgvbghn111111
fffffffgbdghn
fffffff
sfgh3333gs vdf

I need to match any line that has a any character repeated more three or more times in a row.


so i need output like this:
Code:
1111111dffg
dsgvbghn111111
fffffffgbdghn
fffffff
sfgh3333gs vdf
