Lookbehind does not accept variable length arguments — you cannot use “+”, “?”, “*”, or any value x other than n in “{n,[x]}”. You can only group together multiple fixed-length lookbehinds like this:

((?<=[ul ]{14})|(?<=[ul ]{15})),

But I don't think it's necessary — if you already found 14, why would you want to test if there are even more?
