Question

The regular expression is:

^((?!(?<ch>.)\k<ch>\k<ch>)(?!012|123|234|345|456|567|678|789|890)[0-9]){8,}$

The (?!(?<ch>.)\k<ch>\k<ch>) will check for the same character repeated thrice. Note that for the various contiguous sequences I had to put them in a list of possible sequences, (?!012|123|234|345|456|567|678|789|890). [0-9] is the character that will be accepted as valid. The {8,} is for the minimum length.
