A seven-digit phone number \(d_{1} d_{2} d_{3}-d_{4} d_{5} d_{6} d_{7}\) is called "memorable" if the sequence of digits \(d_{1} d_{2} d_{3}\) is the same as \(d_{4} d_{5} d_{6}\) or \(d_{5} d_{6} d_{7}\) (or all three are the same), where \(d_{i}\) can be any digit from 0 to 9. Determine the total number of different "memorable" numbers.
