I believe I've exhausted my det topics.
How about something new?
(A) The set {5,22,59} has the property that the sum of any two is a power. Can you find a larger set? Is there
perhaps THE largest set of X terms?
(B)For the first three odd primes 3^2 +3*5 + 5^2=49=7^2.
Can you find any other a^2 + a*b + b^2 = c^2?
