Pattern matching for identifying repeated numeric sequences

I'm struggling to come up with a regular expression to identify patterns of repeated numbers (more than twice) such as:

1111 or
a1111 or
test4555

Can anyone lend a hand with this, please?

Answer №1

Here is an example of a regex pattern that you can use to match repeated digits:

/(\d)\1\1/

In this pattern, \d represents a digit, (...) is used to capture or remember what was matched inside the parentheses, and \1 refers to the first captured group.
