A card is an arrangement, not a bag: the same squares in different
places win on different lines, so two cards holding the same list are
two different cards.
Type your squares one per line, and the panel above counts every card that
list can make. Then say how many you want and press Deal the
cards: each one is a different arrangement, no two alike, and the
PDF puts one on every page. The seed is printed on the cards, so the same
set can be dealt again. Nothing leaves your browser — the PDF is written
here, byte by byte.
