"Failing admitting speeding, the case will go to court." The point here is that can you have triple gerunds? Or long string of gerunds? "Failing" in this case is a preposition, so it needs to be followed by a gerund. After "admit", you also need a gerund. So is the sentence correct? There is no source, I just made up the sentence. P.S. I'd appreciate it if someone could come up with a long string of continuous gerunds. Just for the heck of it.
