## Technical Note on Rule of Conjunction

When invoking the **Rule of Conjunction** in a tableau proof, use the `{{Conjunction}}`

template:

`{{Conjunction|line|pool|statement|first|second}}`

or:

`{{Conjunction|line|pool|statement|first|second|comment}}`

where:

`line`

is the number of the line on the tableau proof where the Rule of Conjunction is to be invoked`pool`

is the pool of assumptions (comma-separated list)`statement`

is the statement of logic that is to be displayed in the**Formula**column,**without**the`$ ... $`

delimiters`first`

is the first of the two lines of the tableau proof upon which this line directly depends`second`

is the second of the two lines of the tableau proof upon which this line directly depends`comment`

is the (optional) comment that is to be displayed in the**Notes**column.
