I have checked out the iterators thematic tutorial and I must say, it's really helpful. Thank you for recommending that. Seems like the is_king_tableau throws away the tableaux that have 2 in the 2nd-row 1st column. After that, it displays all other tableaux. I tried implementing a condition that goes over the list and throws away the undesired tableaux but haven't been successful yet.
