The answer to yesterday's question is:
1983. They were introduced in Japan in late 1982.
Today's question is:
A pythagorean triple is a set of three whole numbers that form the sides of a right triangle, satisfying the equation a^2+b^2=c^2. For example, 3-4-5 is a pythagorean triple because 3^2+4^2=5^2. The next primitive (no common factors, unlike 6-8-10) pythagorean triple is 5-12-13. If we order the triples based on the smallest “a” value, what is the next pythagorean triple?
