:content: "Let us call an integer sided triangle with sides <var>a</var> ≤ <var>b</var>
≤ <var>c</var> _barely obtuse_ if the sides satisfy \n<var>a</var><sup>2</sup>
+ <var>b</var><sup>2</sup> = <var>c</var><sup>2</sup> - 1.\n\nHow many barely obtuse
triangles are there with perimeter ≤ 75,000,000?\n\n"
