To unlock the case you have to think logically. The T must stand for some thing, the most possible answer in a mathematical word. After thinking for a while I discovered that the T must stand for Triangle or Triangular number. If you think hard there is a triangular number with both the numbers 1 and 6, so it must be the 16th triangular number that is 136. Therefore you have your answer to the problem.
