%N A352316 Perimeter of primitive integer-sided triangles such that the distance d = OI between the circumcenter O and the incenter I is also a positive integer.
%C A352316 For the corresponding primitive triples, miscellaneous properties and links, see A352314.
%C A352316 The sequence is not increasing. For example, a(2) = 128 for triangle with largest side = 48 while a(3) = 120 for triangle with largest side = 55.
%F A352316 a(n) = A352314(n, 1) + A352314(n, 2) + A352314(n, 3).
%e A352316 a(1) = 36 because the smallest triple is (10, 10, 16) with corresponding d = OI = A352315(1) = 5.
%Y A352316 Cf. A231174, A350378, A350379, A352314, A352315.
