  2. There could be alternative Hebrew numerals for hundreds, 500 through 900, based on final forms of letters
  3. Greek and Slavonic numerals can be both in the lower and upper case
  4. Greek numeral for 6 is sigma-tau ligature which resembles by shape an obsolete letter vau or digamma; it can also be written as two separate letters sigma and tau
  5. Greek numeral for 90 is qoppa (an obsolete letter)
  6. Greek numeral for 900 is sampi (an obsolete letter)
  7. Slavonic numerals for 6, 90 and 900 are letters which are not present in the Greek alphabet
  8. The match between Hebrew and Greek/Slavonic numerals breaks at 90 (Hebrew qoph=100, Greek qoppa=90) and thereafter. This is because there is no Greek letter corresponding to tsade: it was dropped from the alphabet when Greeks received it from the Phoenicians
