The number 144 is a natural number with several interesting properties:
- It is the square of twelve (12 × 12 = 144).
- It is the twelfth Fibonacci number, and uniquely in the sequence, it is both a Fibonacci number and a perfect square.
- 144 is known as a "gross," representing a dozen dozens.
- It has mathematical significance, including being the smallest number whose fifth power can be expressed as a sum of four smaller fifth powers, which disproved Euler's sum of powers conjecture.
- Additionally, 144 appears in various interesting numerical patterns and relationships, such as being reversible to 441, which is also a perfect square (21 squared).
- It also finds applications in scale modeling and digital display refresh rates (e.g., 144 Hz monitors).
These notable facts make 144 a remarkable and much-discussed number in mathematics and beyond.
