Rather than searching, you could just use the method described here:
https://en.wikipedia.org/wiki/Pythagorean_triple#Generating_a_triple
and then determine individual upper bounds on m, n, and k (above which
the hypotenuse is necessarily larger than the upper bound of your
desired range).

thanks.... i realized that searching is pretty easy to do...

Some of the triples seem to contain "Twins"

(define (run)
(do ((x 3 (+ 1 x))) ((> x 100))
(do ((y x (+ 1 y))) ((> y 1000000))
(let ((z (sqrt (+ (* x x) (* y y)))))
(if (integer? z)
(begin
(write x) (display " ") (write y) (display " ") (write z) (newline)))))))

a = m^2 - n^2, b = 2mn, c = m^2 + n^2

m = 3, n = 2 -> a = 5, b = 12, c = 13
m = 23, n = 2 -> a = 45, b = 1012, c = 1013
m = 48, n = 47 -> a = 95, b = 4512, c = 4513

and in general
m = 5x+3, n = 5x+2 -> a = 10x + 5
b = 50x^2 + 50x + 12
c = 50x^2 + 50x + 13
and x^2 + x is always even (sum of either two even numbers or two odd
numbers), so this amounts to
b = 100*y + 12
c = 100*y + 13
for some integer y, i.e. b ends in 12 and c ends in 13.

A more involved followup exercise would be to identify similar patterns
where
b = p*10^q + r
c = p*10^q + s
where
p is an integer
q is an integer >= 2
r and s are integers < 10^q
and then see if multiple such patterns form any larger-scale patterns.

there's always a Twin (2-twin or 1-twin) at the end.

wow... every square (A^2) can be expressed as (C^2 - B^2)

what else do you notice ?

Thanks!

Doing that made me notice that I put the code together in a big hurry, and was only finding triples where c is itself a sum of squares (which excludes things like (9, 12, 15) where c is the product of a sum of square and and a non-SOS factor). The whole thing has become a bit of a rabbit hole for me, but here is a possibly pedagogical plot.

i found this 20 min. ago....

watching these clips by 3Blue1Brown (4.59M subscribers) ...
