should we need to escape . ?

/^(?!.*\bgroup\b)(\d{4}) (^.+?.\!\?)$/

is good enough? \. and . does the same thing? any takers?

    Good point that within a character class '.' does not need to be escaped with a backslash. However, you need to use <code></code> tags around it in your post so the [] aren't rendered as links.

    I just copied the OP's pattern. But yeah, 
    /^(\d{4}) ([^\.]+?[\.\!\?])$/

    can be shortened to 

    /^(\d{4}) ([^.]+?[.!?])$/
