Given: The sum of the squares of a and its reverse b (i.e. the number read from right to left) is a perfect square.
Find the sides a,b,c of this peculiar right-angled triangle.
Source: This property was discovered by Victor Thébault in 1959.
(In reply to computer solution
Thébault in 1959 published( American Mathematical Monthly of January 1959) the triplet <Begin>
88209 90288 126225 (7780827681 8151922944 15932750625
corresponding squares) <end>
which triggered my post.
Charlie, your 2 additional solutions (maybe adding one more,
runtime allowing) definitely justify
the adding of 3 interesting sequences (a, b, c) to the OEIS folder.
Strongly recommend you do
