What is the minimum pumping length? In GO’s main site, sachin sir said it as 10 while deepak poonia sir said it as $>=12$…...which of the following is right? According to me 10 should be right as in the question we are choosing at beginning itself what is x that is , is $a$ part or $b$ part and both $a$ and $b$ cannot exist at the same time. So shouldn’t 10 be correct ?
