may vary according to the number of languages in the existing system: in the case of
a two-language system, a third language would require four new transfer modules. The
addition of a fourth language would entail the development of six new transfer modules,
and so on as illustrated in Table 4.1.

Number of languages 2 3 4 5 ... 8 n
Analysis models 2 3 4 5 ... 8 n
Generation models 2 3 4 5 ... 8 n
Transfer models 2 6 12 20 ... 56 n 2 − n
Total models 6 12 20 30 ... 72 n 2 + n
The number of transfer modules in a multilingual transfer system, for all combinations
of n languages, is n 2 − n. Also needed are n analysis and n generation modules, which
