### Output {#output}
**1\) The editor connected all A pages.**
So we have these hreflang tags on the A pages:
```html
```
**2\) The editor connected the B pages 81, 131 and 241 (he has forgotten to connect the swiss B page 191 ;-)).**
So we have these hreflang tags on the B pages 81, 131 and 241:
```html
```
And we have these tags on the swiss B page 191:
```html
```
**3\) The international C page 91 is connected to the german C page 141. And the german C page 141 is connected to the
italian C page 231.**
```html
```
**4\) The swiss C page 181 is not connected to any other page and has a translation.**
```html
```
**5\) The international D page 101 is not connected to another page and has a translation.**
```html
```
**6\) The german D page 151 is not connected to any other page and has no translation, but should be used for Austria, too.**
```html
