First, the largest minimum distance of a ternary cyclic codes of parameters ${[n, \frac{n}{2}]}$ , is determined for n even, not a multiple of 3, by using the Chen algorithm, for n = 26, 34, 38, 46, 50, 58, 62, 68, 70, 74. Next, seven new classes of isodual ternary cyclic codes are introduced for n singly even, not a multiple of 3. %K Cyclic codes %K Minimum distance %K Isodual codes %K 94B15 %K 94B05 %K 94B065 %U http://link.springer.com/article/10.1007/s13373-012-0027-6
