$5\cdot3\cdot4=60$ - the current possible number of plates

after adding 2 letters into the 1st set:
$7\cdot3\cdot4=82$
after adding 2 letters into the 2nd set:
$5\cdot5\cdot4=100$
after adding 2 letters into the 3rd set:
$5\cdot3\cdot6=90$
after adding 1 letter into the 1st set and 1 into the 2nd set:
$6\cdot4\cdot4=96$
after adding 1 letter into the 1st set and 1 into the 3rd set:
$6\cdot3\cdot5=90$
after adding 1 letter into the 2nd set and 1 into the 3rd set:
$5\cdot4\cdot4=80$
