ulong acb_mzeta_mzv_index(const ulong * s, slong r)source

slong acb_mzeta_mzv_index_composition(ulong * s, ulong m)source

Conversions between an admissible index $s$ and the integer $m = (1 y)_2$ where $x_0 y x_1$ is the word of $s$ (written with the digits $0 = x_0$ , $1 = x_1$ ), as in PARI/GP's zetamultconvert: the indices of weight $k$ are $2^{k-2} \le m < 2^{k-1}$ . The first function returns 0 if $s$ is not admissible or its weight exceeds FLINT_BITS; the second writes the index to s (room for $k - 1$ entries) and returns its depth.
