The squares having two components each are AEYL, FBGZ, KA1JD, B1HCI i.e. 4 in number.
The squares having four components each are MRB1W, QNTA, XZUP and YSOV i.e. 4 in number.
The squares having seven components each are AFB1K, EBHA, LZID, and YGCJ i.e. 4 in number.
There is only one square having nine components i.e. MNOP.
There is only one square i.e. ABCD composed of seventeen components.
