Two triangles are considered the same if they have the same three side lengths. Find all possible values of P such that there is only 1 possible triangle with integer side lengths and perimeter P.
Thanks to the answerer in advance! :D
The possible values of P are 3, 4, 5, 6, and 7, so the answer is 3 + 4 + 5 + 6 + 7 = 25.
