    To get the first number after the first (, we can use .*\((\d+). Then to get the first number after the /, we can use /(\d+)\). And then to get the first number after “link”: [lL]ink (\d+). We put these together to get

    ^.*\((\d+)/(\d+)\).*[lL]ink (\d+)

    The three numbers will be in the three groups
