First 11 values of A121387 coincide with apparently unrelated new seq

[franktaw at netscape.net]

There aren't any triple solutions.

This gets a bit deeper into the number theory, but in general the 
number of solutions is 2^(omega(n)-1), where omega(n) is the number of 
distinct prime divisors of n (all of which are = 1 (mod 4)). So, for a 
semiprime, there are always exactly two solutions, except in the case 
of p^2, where there is only one.

Franklin T. Adams-Watters is 100% correct.

The open issue being the multiplicity of such
solutions. The table I gave in seqfans through n=41
shows a number of double solutions, i.e. semiprime
Pythagorean triple hypotenuses in two different ways.

What is the first triple solution?

Perhaps I should make a seq of the first k-tuple
solution of semiprime Pythagorean triple hypotenuses.
Or pehaps not. Thought and feelings?
