A Thabit number is a specific type of integer that is part of a mathematical sequence defined by certain properties. The Thabit numbers are related to the Fibonacci sequence, specifically by being represented as a summation involving Fibonacci numbers. Formally, the n-th Thabit number \\( T_n \\) can be defined as: \\\[ T_n = \\sum_\{k=1\}^\{n\} F_k \\\] where \\( F_k \\) denotes the k-th Fibonacci number.
