Therefore, for example:
i) If in the construction of the word there are 8 of the long tubes, both the name and equation must contain no less than 4 of these tubes. Similarly if in the construction of the name there are 8 of the long tubes, both the word and equation must contain no less than 4 of these tubes.
ii) If the name does not utilise a specific component, then neither the word nor the equation may utilise that component. (The same applies to the word and equation).
