The sefer Yere'im of R. Eliezer of Metz which lists the 613 mitzvos seems to count several identical mitzvos. E.g. mitzvos 25-30 (according to the newer editions). Although I could creatively distinguish between his various descriptions, they seem to overlap. Is there any discussion of this repetition in particular, or of his general approach to counting mitzvos in general?
The following is a summary of the mitzvos in question: 25) Studying Torah 26) Teaching Torah 27) Learning Torah constantly 28) Learning Torah constantly 29) Teaching Torah 30) Learning Torah
