  2. Quintuple meter - Wikipedia

    en.wikipedia.org/wiki/Quintuple_meter

    Simple quintuple meter can be written in 5. 4 or 5. 8 time, but may also be notated by using regularly alternating bars of triple and duple meters, for example 2. 4 + 3. 4. Compound quintuple meter, with each of its five beats divided into three parts, can similarly be notated using a time signature of 15. 8, by writing triplets on each beat of ...

    It is unknown whether these constants are transcendental in general, but Γ(⁠ 1 / 3 ⁠) and Γ(⁠ 1 / 4 ⁠) were shown to be transcendental by G. V. Chudnovsky. Γ(⁠ 1 / 4 ⁠) / 4 √ π has also long been known to be transcendental, and Yuri Nesterenko proved in 1996 that Γ(⁠ 1 / 4 ⁠), π, and e π are algebraically independent.

    For example, when d=4, the hash table for two occurrences of d would contain the key-value pair 8 and 4+4, and the one for three occurrences, the key-value pair 2 and (4+4)/4 (strings shown in bold). The task is then reduced to recursively computing these hash tables for increasing n , starting from n=1 and continuing up to e.g. n=4.
