Kindly help me to find a regex to filter out numbers ending in this pattern

 xxyyxx eg:114411,992299,551155

Thanks in advance

I will leave it to you to bound in \b or otherwise restrict the characters bordering your pattern if required.

(\d)\1(\d)\2(\d)\3

Thanks for the help ddrudik ..

The above pattern matches all repeating digits .eg:112233,332244,...999999

how can i restrict the first and last repeating digits same eg:224422,331133

Thanks for the great help..ddrudik

i figured it out

 This was the requirement

\d\1\d\2\1\1

\d\1\d\2\1\1
