Well upon reflection, I think a good strategy to recall squares, certainly in the range from 32-99 is quite simple. I would simply encode the first three digits of the 4 digit number into ‘major system’ 3 digit code and simply add the last digit by inspection. For example my 73 is GC (George Clooney) I can associate a LeMoN to him (major system to give me 532) and mentally do the 3 x3 = 9 as the last digit. Obviously, numbers squared from 31 down won’t have 4 digits so they can be directly encoded using the major system.
