Furthermore, acquiring the rate modification parameters by which one lipid influences the entry and exit rates of a second lipid allows us to tentatively examine the prospect of compositional homeostasis in more elaborate micellar clusters containing more than two lipid types. For that, we examined the compositional space of micelles comprised of the five employed lipid types (Figure ), and calculated the entry and exit fluxes for the lipids (see Methods). Providing equimolar 4mM lipid concentrations in the environment, we observed that 0.58% of the compositional space "pixels" attains homeostasis. The centroid of the best self-reproducing assemblies contains 21% DPC, 36% SDS, 37.5% DDA, 3% DAS and 2.5% LAU. The self-reproducing compositions are clustered together in space (Figure ), matching the definition of a compotype (cluster of composomes as predicted by the GARD formalism) .
