.SH DESCRIPTION
.B ripser-coeff
computes persistent homology of flag complexes (such as Vietoris-Rips
complexes) only, allowing significant gains in computation time and
memory usage over the general situation. Unlike \fBripser\fR, it
computes over an arbitrary finite field.

See https://arxiv.org/abs/1908.02518 for details.
