I had no idea you could use \1 in the same expression as the tagged group, never seen that before!

Stackoverflow helped me with that one. I knew it was possible, but wasn't sure how. I actually started with the (.)\1* and iterated to the right regex from there.

You should be able to simplify it a little by changing the + to a * so you don't need the second \D I think?
(\D)\1*|(\d+)

Ooh, you're right. I had it that way to start and then ran into problems with a test case that had 663. It was splitting that grouping because it hit the matching case first. But when I removed the capture group generic and made it non-digit that solved that. So can revert back. Thanks :)
