Synopsis
#include <flint/fq_zech_poly_factor.h>int FQ_ZECH_POLY_ITERATED_FROBENIUS_CUTOFF(const fq_zech_ctx_t ctx, slong length)sourceReturns 1 if fq_zech_poly_iterated_frobenius_preinv should use modular composition for a modulus of length length, which is the case if 2 \log_2 q < 3(\lfloor \sqrt{\mathit{length}} \rfloor + 1).
