The major system would assign the "sounds" T + L to the number 15, and then find a word that has those sounds as the first two consonants. Mnemonic images like Tolkien, tiles, or toolbox could be assigned under the major system. In the Dominic system, 15 would be the "letters" A and E, and they would be used as the initials of someone's name—for example, Albert Einstein. Albert Einstein would then be given a characteristic action, such as "writing on a blackboard". Each two-digit number would have an associated person and action.
