0, 1, 8, 144 (EN)

While surfing the Internet I recently found an interesting (although completely incomprehensible) proof of a conjecture stating that 0, 1, 8 and 144 are the only perfect squares in the famous Fibonacci sequence.

For greenhorns: Fibonacci sequence starts with 0 followed by 1, then each subsequent terms is a sum of two preceding terms: 0, 1, 1, 2, 3, 5, 8, 13, 21, 34, … and so on, indefinitely.
