Conclusion: a single party dominating the Scottish parliament is a mathematical impossibility, it cannot be done. This of course applies, mutatis mutandis, to a single pro-independence party dominating the Scottish parliament so as to stop anything like the 1918 Dáil Éireann election result from happening again; when Sinn Féin took 73 (that is 76.7 percent) of the available 105 Dáil seats. Granted, however, this system was not designed with a view to penalising the SNP in particular.
