THREE Triangular Numbers (Posted on 2008-10-21) Difficulty: 3 of 5
Tom, Dick and Harry each chose a different 5-digit triangular number whose digits fell into the pattern THREE, where each different letter represents a different base-10 digit.

Dick's triangular number had no digit in common with either Tom's or Harry's.

What was Dick's number? What two triangular numbers did the other two choose?
