 Counting ARATs (Posted on 2016-09-07)
Let (a, b, c) denote a triplet of distinct integers in an ascending order.
If a2+ b2=c2+1
or if
a2+ b2=c2- 1
we will call such a triplet an ARAT (since it represents an almost-right-angle triangle) .
(4,8,9) is such a triplet.

How many ARATs are there, provided c<1,000,000?
