Question: Consider the language L = { aibjck | i + k = j } . In a proof that L is not regular, you would

Consider the language L

= {

aibjck

|

+

=

} .

In a proof that L is not regular, you would assume L is regular, with pumping length p and then choose a string that causes problems when pumped. Some of the following are designed to make the task easy. Place a check next to each that allows a relatively easy argument that L is not regular.
