EXAMPLE
a(1) = 8; there is one primitive Heronian triangle with perimeter A096468(1) = 12, which is [3,4,5] and the sum of its odd side lengths is 3 + 5 = 8.
a(6) = 52; there are two primitive Heronian triangles with perimeter A096468(6) = 36, [9,10,17] and [10,13,13]. The sum of the odd side lengths is 9 + 17 + 13 + 13 = 52.
